  • Applications

    Copper gluconate (CAS 527-09-3) serves as a source of copper in dietary supplements and animal feeds, providing a micronutrient for essential metabolic functions; it is also used in agriculture as a copper-containing micronutrient for crops and soil health. In cosmetics and personal care, it can function as a trace copper additive in formulations. In cleaning and antimicrobial applications, copper ions from copper gluconate may contribute antimicrobial activity in surface cleaners and sanitizers. Additionally, as a soluble copper salt with gluconate ligands, it can act as a chelating/stabilizing agent and as a copper source in certain polymer or coating formulations where trace metal functionality is desired.
