Isopropyl Alcohol

70% to 99.8% isopropyl alcohol in Lab, USP, ACS, Semiconductor, HPLC, and Reagent grades, in stock and ready to ship.

If you're comparing isopropyl alcohol suppliers, the real question isn't whether they carry it. It's whether the grade you order actually matches what your process needs, since Lab Grade, USP Grade, and Semiconductor Grade IPA aren't interchangeable even at the same concentration.

Lab Alley carries isopropyl alcohol at 70%, 91%, and 99% (or 99.8%), across Lab, USP, ACS, Semiconductor/Electronic, HPLC, and Reagent grades, priced and in stock online so you can match grade to application without a quote call. USP Grade 99.8% and 91% carry Kosher and Halal certification, and USP Grade 70% is Halal certified, with SDS and COA available for every grade we sell.

About Isopropyl Alcohol

Isopropyl Alcohol (C₃H₈O), also known as Isopropanol and commonly sold in stores as rubbing alcohol is a colorless, flammable liquid, that is volatile, easily turns into a vapor with a mild odor, and can be mildly irritating to the eyes, nose and throat.

Isopropyl Alcohol is an essential component of many cosmetics, used as a disinfectant in medical facilities and homes, and widely used as a solvent in chemical industries. It is commonly manufactured by direct and indirect hydration (a reaction with water) of propylene, C₃H₆.

Compared to other common solvents and alcohols isopropyl alcohol has relatively low toxicity.

About Isopropyl Alcohol

Isopropyl alcohol (IPA), also called isopropanol or 2-propanol, is a colorless, volatile, flammable liquid with the formula C3H8O and a molecular weight of 60.10. It's commercially produced by direct or indirect hydration of propylene and has a flashpoint around 12°C (53°F), which classifies it as a Class IB flammable liquid. Compared to many common solvents, IPA has relatively low toxicity, though its vapor can still irritate the eyes, nose, and throat, and prolonged storage can lead to explosive peroxide formation, so older stock should be tested before distillation or evaporation.

COMMON APPLICATIONS

Isopropyl alcohol is used as a reagent, disinfectant, and antiseptic agent, a general industrial and laboratory solvent, an ingredient in soap making and cosmetics, and a cleaning solvent in electronics manufacturing.

GRADES EXPLAINED

Lab Grade IPA has reasonable purity for general solvent, cleaning, and disinfecting use, but its exact impurity profile isn't controlled to an official standard, so it isn't suited to food or drug applications. USP Grade meets United States Pharmacopeia purity requirements for medical and personal-care formulation, which is why most of our USP-grade SKUs also carry Kosher and Halal certification. ACS Grade meets American Chemical Society reagent specifications for analytical chemistry. Semiconductor/Electronic Grade is an ultra-high-purity IPA formulated for low-residue electronics cleaning, and HPLC Grade meets the purity chromatography instrumentation requires. Reagent Grade Anhydrous 2-Propanol (≤30ppm water) is for moisture-sensitive reactions and applications where even trace water is a problem.

TYPES & GRADES AT A GLANCE

Lab Grade (70%, 91%, 99.8%)

Is general-purpose IPA for cleaning, disinfecting, and non-critical solvent use.

USP Grade (70%, 91%, 99.8%)

Meets pharmacopeial standards for medical, drug, and personal-care formulation; most SKUs are Kosher and Halal certified.

ACS Grade, 99.8%

Is analytical reagent grade for chemistry labs needing tight impurity limits.

Semiconductor/Electronic Grade, 99%

Is ultra-high purity for electronics manufacturing and precision cleaning.

HPLC Grade, 99%

Is chromatography-grade purity for HPLC, GC, and other analytical instrumentation.

Reagent Grade, Anhydrous (≤30ppm H2O)

Is for moisture-sensitive reactions and applications needing near-zero water content.

Frequently Asked Questions

What's the difference between Lab Grade and USP Grade isopropyl alcohol?

Same percentage on the label doesn't mean the same product. Our 99.8% Lab Grade specs out at a minimum 99.8% assay and 20 ppm nonvolatile residue, solid numbers, but nobody's testing it against a pharmacopeial method. So if a regulator or an ingredient buyer ever asks for pharmacopeial compliance, Lab Grade has nothing to show them. USP Grade does, tested to United States Pharmacopeia requirements, and it's the only grade family we carry that's also Kosher and Halal certified. Anything touching skin or a drug formulation, go USP.

What does 70%, 91%, and 99% isopropyl alcohol mean, and which should I use?

Water's doing more work than people think. 70%, 91%, and 99% are all IPA by volume with water filling the rest, and that water actually makes 70% the better disinfectant, not the weaker one. It slows evaporation just enough for the alcohol to get into a microorganism's cell wall before it flashes off. Push it to 99% and it can evaporate too fast to finish the job on a hard surface. That's backwards from what most people guess, and it's why hospitals standardize on 70% for hand rubs while electronics shops standardize on 99% or 99.8%, where fast evaporation and low water content matter more.

Do I need a permit to buy isopropyl alcohol?

No permit, no paperwork. People who've bought SDA or denatured ethanol from us sometimes expect a TTB form to show up somewhere, but isopropyl alcohol was never a beverage-alcohol product in the first place. Order it like anything else in the catalog.

Which isopropyl alcohol products are Kosher or Halal certified?

USP 99.8% and USP 91% carry both Kosher and Halal. USP 70% is Halal only, no Kosher. Lab, ACS, Semiconductor/Electronic, and HPLC and Reagent Grade: none of them are certified either way right now. If a label claim matters to you, stick to USP.

Can isopropyl alcohol be shipped to a residential address?

No. IPA ships DOT Class 3 flammable liquid, UN1219, Packing Group II, and that means business, school, university, or lab addresses only. Put a residential address at checkout and we'll pull the item before it ships rather than risk it getting flagged in transit. Save yourself the back-and-forth and use a commercial address from the start.

Which grade should I use for electronics cleaning versus HPLC versus general lab work?

Depends what you're doing with it. Semiconductor/Electronic Grade 99% is built to leave next to nothing behind, which matters on a circuit board in a way it doesn't on a lab bench. HPLC Grade 99% is there because chromatography instruments need that specific purity; don't substitute a cheaper grade to save a few dollars. Everything else, general lab and research work, any Lab Grade concentration (70%, 91%, 99.8%) gets the job done for less.

How does isopropyl alcohol compare to ethanol for disinfecting?

Both work as disinfectants at the right strength. IPA just evaporates a little slower than ethanol and leaves less residue, which is most of the reason it's the default base for hand sanitizers instead of ethanol. Need a Kosher, Halal, or food-grade alcohol for something that isn't disinfecting? Check our Ethanol category instead. For disinfecting or electronics cleaning, IPA's usually the cheaper, simpler call.

Can I buy isopropyl alcohol in drums or totes?

Yes, mostly. Standard IPA grades go up to 55-gallon drums, some concentrations up to 270-gallon totes. Semiconductor, HPLC, and Reagent Grade stay in smaller lab-pack sizes because that's genuinely how people buy them, not because we're out of bulk. Check the product page or just call before you assume a bulk size is sitting in stock.
