Description

Diglycolic Acid CAS NO 110-99-6 is a versatile dicarboxylic acid derivative of diethylene glycol, valued for its bifunctional reactivity as both an acid and an ether. This compound is a critical intermediate in the synthesis of high-performance polymers, chelating agents, and specialty chemicals. It is essential for manufacturers in the polymer, pharmaceutical, and personal care industries seeking to create products with enhanced stability, solubility, or complexing properties.

Application

• Polymer Synthesis: Key monomer for producing polyesters, polyamides, and other condensation polymers, imparting flexibility and chemical resistance.
• Chelating Agents: Serves as a precursor for the manufacture of biodegradable and high-efficiency chelants used in water treatment, detergents, and textile processing.
• Pharmaceutical Intermediates: Used in the synthesis of active pharmaceutical ingredients (APIs) and prodrugs, leveraging its carboxylic acid groups for conjugation.
• Crosslinking Agent: Functions as a crosslinker in resins and coatings to improve hardness, durability, and thermal stability.
• Personal Care & Cosmetics: Employed in the formulation of skin care products as a pH adjuster and a building block for emulsifiers.
• Adhesives & Sealants: Modifies the properties of adhesive formulations to enhance bonding strength and environmental resistance.
