PLGA Ester Capped (75:25), MW 5K is a medium-low molecular weight, ester-terminated poly(D,L-lactide-co-glycolide) random copolymer with a 75:25 lactide to glycolide molar ratio. Featuring inert, non-reactive ester end groups, this high-purity biodegradable polymer possesses stable chemical properties and requires no additional chemical activation for conventional biomedical and pharmaceutical formulations. The standard 75:25 monomer composition enables steady and uniform hydrolytic degradation, supporting reliable medium-term drug release performance for various delivery systems. The material exhibits excellent biocompatibility and complete biological safety, fully degrading into natural non-toxic lactic acid and glycolic acid within living organisms. Supplied as fine white amorphous powder, the polymer dissolves readily in common organic solvents such as DCM, chloroform, THF and acetone. Store the product in a tightly sealed container at -20°C under dry and dark conditions to maintain stable molecular weight and consistent product performance.
