  • Applications

    4-Hydroxyvaleric acid (CAS 13532-37-1) is primarily applied as an industrial intermediate. In the polymers/plastics area, it functions as a reactive building block that can form polyesters via esterification and can be converted to delta-valerolactone, a versatile monomer for biodegradable polyesters and related plasticizers. In coatings, inks and adhesives, its dual functionality (hydroxyl and carboxyl groups) enables resin modification and crosslinking. The compound is also used as a precursor for fragrance-related esters and other derivatives in perfumery and cosmetics, and may serve as a starting material in pharmaceutical and agrochemical syntheses. Overall, its role is that of an intermediate and feedstock, with applications governed by formulation requirements and regulatory considerations.
