Description

Zinc Cysteinate Hydrochloride is a specialized coordination complex of zinc with the amino acid cysteine, supplied as its hydrochloride salt. This compound is valued for its role as a bioavailable source of zinc and a precursor in the synthesis of advanced materials and pharmaceutical intermediates. It is primarily utilized by manufacturers in the nutraceutical, pharmaceutical, and cosmetic industries for applications requiring stabilized, soluble zinc complexes.

Application

• Nutraceutical & Dietary Supplements: As a bioavailable zinc source in mineral supplements and functional food fortification.
• Pharmaceutical Intermediates: Used in the synthesis of specialized drugs and as an active pharmaceutical ingredient (API) in topical formulations.
• Cosmetic & Personal Care: Incorporated into skincare products for its potential antioxidant and skin-conditioning properties.
• Biochemical Research: Serves as a reagent in enzymatic studies and metalloprotein research.
• Animal Nutrition: Used as a trace mineral supplement in premium animal feed formulations.
• Chelated Fertilizers: Acts as a micronutrient component in high-efficiency agricultural products.
