Cupric Nitrate
Buy Copper (Cupric) Nitrate Trihydrate in Lab, Purified and ACS Grade, Plus a Ready to Use 1.0 Molar Solution.
Buy cupric nitrate online in the exact grade your process calls for, without waiting on a quote for four small jars of crystal. This is a small, focused category, just 4 products, so there's no long list to sort through. The core item is Copper (Cupric) Nitrate Trihydrate, Cu(NO3)2·3H2O, sold as dark blue crystal in Lab Grade, Purified Grade and ACS Grade. If you'd rather skip weighing crystal and dissolving it yourself, there's also a ready mixed 1.0 Molar solution in liter bottles.
Every product here has its SDS and COA available online, and the ACS grade specification sheet lists exact limits for chloride, sulfate, iron and several other trace metals, so analytical buyers can confirm the numbers before ordering. Sizes for the crystal run from 100 g jars up to 200 lb drums, and the solution ships as a 1 liter bottle. None of these products are Kosher, Halal or food grade certified.

Cupric Nitrate - 4 products About Cupric Nitrate
Cupric nitrate, also called copper (II) nitrate or copper dinitrate, is the nitrate salt of copper. The common trihydrate form, Cu(NO3)2·3H2O, is a dark blue, hygroscopic crystalline solid with no odor, and it's fully soluble in both water and alcohol. Because it's hygroscopic, it pulls moisture from the air, so containers need to stay tightly closed between uses. Heated to decomposition, it gives off toxic nitrogen oxide and copper oxide fumes, so it shouldn't be heated in an open or poorly ventilated space. Lab Alley also carries an anhydrous 1.0 molar solution, which is 18.8% cupric nitrate by weight dissolved in water and appears as a blue green liquid rather than crystal.
COMMON APPLICATIONS
Reagent and chemical precursor work in general lab and analytical settings, textile processing and dyeing, polishing and finishing of metals, electroplating baths, and use as a catalyst in some organic synthesis. It's also been used historically as a fungicide, herbicide and insecticide precursor, though most of Lab Alley's customers buy it for reagent, textile or metal finishing use rather than agricultural applications.
GRADES EXPLAINED
Lab Grade is solid, everyday purity with no official monograph, and the practical choice for general reagent use, textile work and metal polishing. Purified Grade, sometimes called Pure or Practical Grade, sits a step above Lab Grade but still doesn't meet ACS, USP or FCC specifications, and is often used alongside Lab Grade chemicals. ACS Grade is tested against American Chemical Society limits on chloride, sulfate, iron, sodium, potassium, calcium, nickel and lead, and it's the one to buy for analytical methods or anywhere trace metal levels matter.

Frequently Asked Questions
Where can I buy cupric nitrate online?
Right here. We carry cupric nitrate trihydrate crystal in Lab, Purified and ACS grade, plus a ready mixed 1.0 molar solution. Pick the grade and size, check the price, and order with no quote needed. Most in stock orders ship within 1 to 2 business days.
What is the formula and molar mass of cupric nitrate?
The trihydrate crystal we sell is Cu(NO3)2·3H2O, with a molecular weight of about 241.6 g/mol. The anhydrous form, used in our 1.0 molar solution, is Cu(NO3)2 with a molecular weight of about 187.6 g/mol. That difference matters if you're converting between our crystal and solution products for a recipe or a calculation.
Crystal or solution: which cupric nitrate should I buy?
If you need a specific molar concentration for a lab procedure and want to skip weighing and dissolving crystal yourself, the 1.0 Molar solution is the faster option. If you need dry crystal for textile work, metal polishing, or a custom concentration you'll dilute yourself, one of the trihydrate crystal grades gives you more flexibility.
Lab, Purified or ACS grade: what's the difference?
It comes down to purity and testing. Lab Grade is solid, general purpose purity with no official standard behind it. Purified Grade sits a step above Lab Grade but still isn't tested to ACS, USP or FCC limits. ACS Grade is the one that's actually tested against American Chemical Society specifications for chloride, sulfate, iron and several other trace metals, so it's the grade to buy for analytical work.
Is your cupric nitrate Kosher, Halal or food grade?
No. None of the four cupric nitrate products on this page carry Kosher, Halal or food grade certification. They're sold for laboratory, textile, metal finishing and industrial use. Each product does have an SDS and lot specific COA on its page, so you can check the exact specs before ordering.
Do I need a permit, and can cupric nitrate ship to my home?
No purchase permit is required. Cupric nitrate does ship as a DOT regulated oxidizer, listed as an inorganic nitrate under UN1477, Packing Group III. Plan on a business, lab or school address rather than a home delivery for the crystal grades. Each product page lists its shipping details, and Customer Care at 512-668-9918 can confirm before you order.
What is cupric nitrate used for?
Mainly as a reagent and chemical precursor in labs, plus textile processing and dyeing, polishing and finishing metals, and electroplating baths. It has also been used as a catalyst in some organic synthesis. It is not intended for food, agricultural or consumer use, so check the SDS before using it for anything outside standard lab or industrial applications.
Can I buy cupric nitrate in bulk?
Yes, the crystal grades scale up to 25 kg and 200 lb containers right on the product page, so a lot of what would be a bulk request elsewhere is already available to order directly. For anything larger, or a recurring delivery schedule, request pricing through Bulk & Custom Chemicals. Autoship takes 10% off eligible repeat orders.
How should cupric nitrate be stored?
Keep it tightly sealed in its original container, since the trihydrate crystal is hygroscopic and will absorb moisture from the air if left open. Store it in a cool, dry, well ventilated area away from combustible materials and organic solvents, since it's classed as an oxidizer. Check the SDS for full storage and incompatibility details before handling larger quantities.
