What is Copper nitrate trihydrate?
Copper nitrate trihydrate (CAS 10031-43-3), also sold as cupric nitrate trihydrate, is a water-soluble copper salt.
Where is Copper nitrate trihydrate used?
- Catalyst manufacturing: precursor for copper oxide catalysts used in hydrogenation, oxidation and exhaust gas treatment
- Textile and leather processing: mordant that fixes colorants and improves wash fastness
- Printed circuit boards and metal finishing: etching, patination and surface oxidation of copper and copper alloys
- Agriculture: copper-source micronutrient in foliar sprays and soil correction products for copper-deficient crops
- It provides a practical source of Cu²⁺ ions where consistent metal delivery matters.
Good to know: Store in a cool, dry area away from combustible materials due to its oxidizing properties.
Commercial specifications
- Purity typically 98% to 99%+
- Bulk supply in 25 kg bags or drums
