Description
Chromium(III) Nitrate Product Overview
Chromium(III) nitrate usually comes as the nonahydrate (Cr(NO3)3·9H2O, CAS 7789-02-8), which forms violet crystals that dissolve easily in water. Because chromium is trivalent, it is far less hazardous than hexavalent compounds such as Chromic Acid, although the nitrate is an oxidizer.
Catalyst producers use it to impregnate supports for chromium oxide catalysts, because the nitrate decomposes cleanly on calcination. Similarly, chemists use it as a soluble chromium source in synthesis and sol-gel processes, and textile producers use chromium salts as mordants. It also serves in some corrosion inhibitor and surface treatment formulations.
Furthermore, other trivalent chromium compounds in our range include Chromium (III) sulfate hydrate and Chromium Oxalate Solution.

⚠️ Safety & Handling: Oxidizing solid that may intensify fire; may cause skin and eye irritation and allergic skin reactions. Keep away from combustible materials and also wear gloves and eye protection. Store in tightly closed containers away from reducing agents and strong oxidizers, which could form toxic chromium(VI). Always consult the Safety Data Sheet (SDS), because it contains the full classification and handling instructions.
Frequently Asked Questions
Is chromium(III) nitrate the same as chromic acid?
No. Chromium(III) nitrate contains trivalent chromium and is far less hazardous, whereas chromic acid contains hexavalent chromium.
Which form do you supply?
The nonahydrate is standard, because it is the stable commercial form.
How can I get a price and documents?
Prices depend on quantity, packaging and destination, so please contact us with your required volume. We then send a quotation together with the CoA and SDS.
