Copper(ii) nitrate trihydrate

Copper(II) Nitrate Trihydrate (CAS 10031-43-3, EC 600-060-3), also known as Cupric Nitrate Trihydrate or Copper Dinitrate Trihydrate, is an inorganic copper salt supplied as a hygroscopic blue crystalline fine powder. It carries no assigned E-code and is classified under HS code 28342930 within the Salts & Minerals category.

In textile and leather processing, it functions as a mordant and preservative by releasing copper ions that bind to fibres and inhibit microbial degradation. In catalysis applications, it serves as a copper source in nitration reactions and metal oxide catalyst preparation. Water treatment operations use it to inhibit corrosion by forming protective copper-based surface films on metal infrastructure.

This material is available in technical and reagent grades, supplied in compliance with REACH regulations applicable to EU markets. Standard packaging formats include multi-layer bags and drums suited to bulk procurement. Buyers should confirm grade specifications against application requirements prior to ordering.
