Description

Calcium Galactarate is a calcium salt of galactaric acid (mucic acid), offering a stable and bioavailable source of calcium ions. This compound is valued for its role as a functional additive and intermediate in industries requiring precise mineral fortification or controlled chemical synthesis. It is particularly relevant for manufacturers in the pharmaceutical, nutraceutical, and specialty chemical sectors seeking consistent quality and reliable supply.

Application

• Pharmaceutical Excipient: Used as a calcium source in tablet formulations and as a buffering agent in certain medicinal products.
• Nutraceutical & Dietary Supplements: Serves as a calcium fortification agent in vitamin and mineral supplement blends.
• Food Additive: Functions as a firming agent, stabilizer, or nutrient supplement in specialized food products.
• Chemical Synthesis: Acts as a key intermediate or starting material in organic synthesis for producing derivatives of galactaric acid.
• Laboratory Research: Utilized as a standard or reagent in biochemical and analytical research applications.
• Cosmetic Formulations: May be incorporated into personal care products for its mineral content and stabilizing properties.
