Essential Chemicals (Top Sellers)

Buy our best selling chemicals online, from ethanol and isopropyl alcohol to acids and solvents, in sizes from a single bottle to a 270 gallon tote.

You already know what you need. You just want to order it at a fair price, get it in a few days, and get back to work. That's what Essential Chemicals (Top Sellers) is for. It gathers the chemicals our customers reorder most, so you can skip the searching and the quote requests and buy online with the price, size and grade right in front of you. Think of it as the short list of chemicals that keep labs, shops and production floors running. You'll find ethanol in 200 proof and 140 proof, isopropyl alcohol in 70% and 99.8%, Lab Grade acetone, and hydrogen peroxide from 3% to 34%. Sodium hypochlorite is here, along with nitric, sulfuric and hydrochloric acid, and solvents like heptane and toluene. Some products are Food Grade, many are Lab Grade, and a few carry Kosher or Halal certification. The product name always tells you which.

Plenty of suppliers make you wait on a rep for pricing, then chase paperwork once the order lands. We'd rather you didn't have to. Every product page shows its sizes and price, and the Safety Data Sheet and Certificate of Analysis are online whenever your quality team asks for them. Orders ship from U.S. inventory in 1 to 2 business days, and sizes run from small bottles to 55 gallon drums and 270 gallon totes, so the same page works for a teaching lab and a production line. You pick the chemical, choose a size and check out in minutes, and Autoship is available on many products if you'd rather not reorder by hand. A few chemicals here, like mercury and dichloromethane, have address or eligibility rules, and the FAQ below explains them so checkout holds no surprises. If you need a size or volume you don't see, request a quote and we'll build it around your order.

About Essential Chemicals (Top Sellers)

These aren't one chemical, so there isn't one set of properties. But the top sellers fall into a few families, and each family behaves its own way. Knowing which one you're buying makes storage, handling and ordering a lot easier.

Alcohols and solvents. Ethanol, isopropyl alcohol, acetone, heptane and toluene are flammable liquids that evaporate quickly. Ethanol 200 proof, for example, has a flash point of 14.0°C (57.2°F), so its vapors can ignite below normal room temperature if a flame or spark is nearby. Flammable liquids ship as hazmat, and a hazmat fee can apply. Keep them tightly closed, cool and away from heat.

Oxidizers. Hydrogen peroxide and sodium hypochlorite react with whatever they touch, and they lose strength as they age. Hydrogen peroxide breaks down into water and oxygen. Sodium hypochlorite weakens with heat and light, and you should never mix it with acids or ammonia, because that releases toxic gas.

Strong acids. Nitric, sulfuric and hydrochloric acid, along with trichloroacetic acid at 85%, are corrosive. Wear gloves and eye protection, and check the Chemical Storage Compatibility Chart before you shelve one next to anything else.

COMMON APPLICATIONS

Cleaning and disinfecting. Isopropyl alcohol at 70% is a common surface disinfectant. At 99.8% it contains very little water, so it dries fast and leaves little behind, which suits equipment and electronics. Sodium hypochlorite and hydrogen peroxide are used for sanitizing, and sodium hypochlorite is also used in water treatment.

Extraction, food and formulation. Ethanol 200 proof goes into botanical and herbal extraction, flavor extracts, fragrance and cosmetic formulations, and pharmaceutical and nutraceutical processing. The undenatured Food Grade version is the one to pick when the product ends up in or on something people use.

Lab and teaching work. Acetone is a go to for rinsing glassware and removing residues, and hydrogen peroxide solutions turn up in classroom demonstrations. Solvents like heptane and toluene, and reagents like glycolic acid, round out everyday bench work.

Industrial processing. Nitric, sulfuric and hydrochloric acid are used for metal cleaning and treatment, pH adjustment, and as lab reagents. Ethylene glycol and other solvents on this page also support production and maintenance jobs.

GRADES EXPLAINED

Lab Grade is the grade on much of this page. It's a good fit for general lab work, teaching, cleaning and industrial use, where you don't need a guaranteed impurity limit.

ACS Reagent Grade meets purity standards set by the American Chemical Society. Choose it when your method or your auditor calls for tight, documented purity, like analytical work.

USP/FCC Food Grade means the product meets United States Pharmacopeia and Food Chemicals Codex requirements, so it can go into pharmaceutical and food applications. Ethanol 200 Proof Undenatured on this page is USP/FCC Food Grade.

Proof versus percent. For ethanol, proof is double the percentage by volume. So 200 proof is 100%, 190 proof is 95%, and 140 proof is 70%. Other chemicals here, like isopropyl alcohol and hydrogen peroxide, use plain percentages.

Kosher and Halal are certifications, not grades, and they apply only to select products. If the product name doesn't say Kosher or Halal, it isn't certified.

For a plain language look at how grades compare, read our Chemical Grades guide.

Frequently Asked Questions

What's the difference between denatured and undenatured ethanol?

Undenatured ethanol has nothing added to it, which is why it fits food, flavor and pharmaceutical work. Denatured ethanol has denaturants mixed in so it can't be consumed as a drink, which makes it a practical pick for cleaning, extraction and general solvent use. Both 200 proof listings on this page carry Kosher and Halal certification, so check the product name for the exact form you're getting.

What does 200 proof mean, and how does it compare to a percentage?

For ethanol, proof is double the alcohol percentage by volume. So 200 proof is 100%, 190 proof is 95%, and 140 proof is 70%. Isopropyl alcohol and hydrogen peroxide use plain percentages instead, like 70% or 99.8% isopropyl alcohol and 3% to 34% hydrogen peroxide. A higher number means less water in the bottle. That matters when water would interfere with your process, and it matters less for general cleaning.

Do I need a permit to buy these chemicals?

Not for every product, but a few carry extra steps. Specially denatured alcohol (SDA) in 5 gallons or more requires a TTB permit, which you email to customer care with your order number. Dichloromethane requires an EPA eligibility form at checkout, and the order doesn't ship until it's approved. Check the Safety and Shipping section on the product page, since the rules depend on the chemical and the size.

Which of these chemicals are Kosher or Halal certified?

Only select products carry Kosher or Halal certification, and the product name tells you which. Among the top sellers, Ethanol 200 Proof Undenatured, Denatured Ethanol 200 Proof and Ethanol 140 Proof Denatured are listed as Kosher and Halal, and Deionized Water Lab Grade is listed as Kosher. If the name doesn't say Kosher or Halal, the product isn't certified. Lab Alley itself is ISO 9001 certified for quality management.

Can these chemicals ship to a home address?

Some can't. A few chemicals ship only to businesses, schools, universities and laboratories, and a restricted item in a residential order is removed before shipping. Mercury has its own limits. More than 1 lb must go to a commercial address, lab or school, and mercury doesn't ship to apartments, parcel stores or Canada. Some products ship only to facilities set up to handle them safely, so check the product page before you check out.

Which grade should I choose for cleaning, analysis or food work?

Match the grade to the job. Lab Grade suits general lab work, teaching, cleaning and industrial use, and it's the grade on much of this page. Pick ACS Reagent Grade when your method calls for tight, documented purity, like analytical work. Choose USP/FCC Food Grade when the product goes into food, flavors or pharmaceutical processing. If your protocol or auditor names a grade, follow it and ask us before you swap anything.

How is isopropyl alcohol different from ethanol for cleaning and disinfecting?

Both work as cleaners and disinfectants, but they aren't interchangeable. Isopropyl alcohol is the cleaning workhorse, with 70% the common pick for disinfecting surfaces and 99.8% for fast drying jobs like equipment and electronics. Ethanol comes in undenatured, Food Grade, Kosher and Halal forms, so it's the one for extraction, flavors and formulation. Isopropyl alcohol isn't meant for anything people consume.

Can I buy these chemicals in drums or totes?

Yes. Sizes on this page run from small bottles up to 55 gallon drums and 270 gallon totes, and a few items go as high as 310 gallons. Not every chemical comes in every size, so use the size filter on the page to see what's offered. For pallet volumes or a size you don't see, send a quote request or visit our Bulk & Custom Chemicals page.

Can I set up repeat orders for chemicals I use every month?

Yes, for many of them. Products with Autoship let you pick a schedule, from every week up to every 12 weeks, and some offer a discount when you subscribe. Ethanol 200 Proof Undenatured, for example, offers 10% off with Subscribe and Save. Use the Autoship filter on this page to see which chemicals qualify, then set it up right on the product page.

Where do I find the SDS and Certificate of Analysis?

Both are online, so you don't need to ask a rep. Open any product page and look under Business Support and Product Manuals. Many pages also include certificates and compliance statements, such as the Kosher, Halal and GRAS documents on the Ethanol 200 Proof page. You can also browse every Safety Data Sheet and Certificate of Analysis from the Resources menu.
