PLGA Diacid structure

 

Description

General Description

PLGA Diacid is a biodegradable polyester synthesized from D,L-lactide and glycolide and terminated with carboxylic acid groups at both ends of the polymer chain. The polymer combines the excellent biodegradability and biocompatibility of PLGA with highly reactive carboxyl functionalities suitable for further chemical modification.

The terminal carboxyl groups can be activated using carbodiimide chemistry (EDC/NHS) and subsequently conjugated with amines, peptides, proteins, PEG derivatives, targeting ligands, and therapeutic molecules. PLGA Diacid serves as an important intermediate for the synthesis of functional block copolymers, targeted drug delivery systems, nanoparticles, and biodegradable biomaterials.
