Copper citrate

Copper citrate (CAS 10402-15-0) is an inorganic copper salt of citric acid; a source of bioavailable copper and a broad-spectrum biocide.

Where is Copper citrate used?

• Agriculture: registered pesticide and fungicide active ingredient controlling fungal and bacterial pathogens on crops
• Food and feed: copper fortification agent in nutritional premixes
• Mineral supplements and animal feed: soluble, chelated copper source
• Water treatment: algae and microbial control in industrial cooling systems and potable water
• Pharmaceutical manufacturing: copper source in parenteral nutrition solutions and micronutrient supplement formulations
• Its chelated structure allows controlled copper release for sustained activity or nutritional delivery.

Good to know: Chelated copper is preferred over inorganic sulfates where bioavailability must be balanced against phytotoxicity risk.

Commercial specifications

• Bulk packaging in fiber drums or bags; smaller quantities for laboratory and formulation development
