Description

Glucaric Acid CAS NO 25525-21-7 is a naturally occurring dicarboxylic acid derived from glucose, serving as a key building block for sustainable chemistry. This versatile compound is valued for its chelating, sequestering, and acidifying properties, making it a crucial intermediate for high-value derivatives. It is essential for manufacturers in the detergent, polymer, corrosion inhibitor, and pharmaceutical industries seeking bio-based alternatives.

Application

• Detergent Builder & Chelating Agent: Used as a biodegradable, non-phosphate alternative to traditional builders like phosphates and EDTA for water softening and scale inhibition.
• Polymer & Resin Intermediate: A key monomer for producing bio-based polyesters, nylons (polyhydroxyamides), and other specialty polymers.
• Corrosion & Scale Inhibitor: Effective in industrial water treatment and cooling tower applications to prevent mineral scale and corrosion.
• Pharmaceutical & Nutraceutical Synthesis: An important precursor for compounds like D-glucaro-1,4-lactone, which is studied for various therapeutic applications.
• Food Additive & Acidulant: Potential use as a food-grade acidulant and preservative, contributing to tartness and microbial control.
• Metal Surface Treatment: Employed in metal cleaning, plating, and finishing processes due to its effective chelation of metal ions.
• Concrete Admixture: Acts as a set retarder and water reducer in concrete formulations to improve workability and final strength.
