Description

Zinc Tartrate is an inorganic salt of zinc and tartaric acid, known for its role as a versatile intermediate and functional additive. This compound is valued for its ability to provide a bioavailable source of zinc in specialized formulations and its utility in controlled chemical synthesis. It is primarily sought by manufacturers in the nutritional supplement, pharmaceutical, and specialty chemical industries for applications requiring precise metal ion delivery and chelation properties.

Application

• Nutritional & Dietary Supplements: As a source of bioavailable zinc in mineral fortification blends and vitamin-mineral complexes.
• Pharmaceutical Intermediates: Used in the synthesis of active pharmaceutical ingredients (APIs) and as an excipient in certain tablet formulations.
• Catalyst & Chemical Synthesis: Serves as a precursor or catalyst in organic synthesis and specialized polymerization processes.
• Laboratory & Research Reagents: Employed in analytical chemistry and life science research as a standard or reagent.
• Specialty Additives: Functions in niche applications such as corrosion inhibitors, stabilizers, or in electroplating baths.
