Cupric citrate

Cupric citrate (CAS 866-82-0), also known as copper citrate, is an inorganic copper salt; a source of bioavailable copper and a chelating agent.

Where is Cupric citrate used?

• Food and dietary supplements: copper mineral fortifier in infant formulas, multivitamins and functional foods
• Pharmaceuticals: copper source in parenteral nutrition solutions and oral mineral preparations
• Agriculture: micronutrient additive in animal feed premixes and fertilizer blends
• Antimicrobial coatings and preservation systems: biocidal action via slow copper ion release
• It binds metal ions and delivers controlled copper content where ionic copper alone would be too reactive or unstable.

Good to know: Purity levels and copper content declarations vary by grade; buyers should confirm specification sheets against their formulation requirements to ensure the product meets all necessary safety standards.

Commercial specifications

• Some suppliers offer material compliant with USP or FCC monographs
