Copper nitrate

Copper nitrate (CAS 3251-23-8), also sold as cupric nitrate, is an inorganic copper salt used industrially as an oxidizing agent, catalyst precursor, and biocidal active.

Where is Copper nitrate used?

• Water treatment: biocide and algaecide
• Industrial cooling systems and process water circuits: controlling microbial growth
• Textile and leather processing: mordant and surface treatment agent that fixes dyes and imparts antimicrobial finishes
• Catalyst manufacturing: copper precursor for supported metal oxide catalysts used in chemical synthesis and emissions control
• Agriculture: micronutrient copper source in foliar sprays and soil correction for copper-deficient crops
• It delivers soluble copper ion in concentrated, reactive form.

Commercial specifications

• Purity specifications typically 98% to 99%
• Bulk quantities in bags or drums suited to moisture-sensitive handling
