Copper(II) nitrate

Copper(II) nitrate, also known as cupric nitrate or CU(NO3)2, is an inorganic copper salt commercially available under the trade name Claycop. It carries CAS number 3251-23-8 and EC number 221-838-5. No E-code designation applies to this substance.

In agriculture and water treatment, copper(II) nitrate functions as a biocide by releasing copper ions that disrupt microbial cell membranes, inhibiting bacterial and algal growth. In mining and metal processing, it serves as an oxidising catalyst in nitration and etching reactions, activating metal surfaces through controlled oxidation.

Copper(II) nitrate is supplied as a technical-grade crystalline solid and is subject to REACH registration requirements within the European Union. Procurement quantities typically range from laboratory-scale packaging to bulk industrial formats. Buyers should verify supplier documentation for purity specifications and compliance with applicable handling and transport regulations for oxidising substances.
