PLGA-di-acid, MW 10K

PLGA-di-acid, MW 10K is a medium-molecular-weight linear biodegradable polyester capped with carboxylic acid groups at both molecular terminals. Formed by copolymerizing D,L-lactide and glycolide monomers, this polymer covers mainstream LA/GA ratios including 50:50, 65:35, 75:25, and 85:15, with custom ratio support for tailored research demands. Balancing moderate chain length and stable chemical activity, the 10K PLGA-diacid avoids the overly fast degradation of low-molecular variants while retaining reliable carboxyl reactivity for common bioconjugation reactions. Dual-terminal -COOH groups enable stable amide bond formation, surface functionalization, and block copolymer construction, making it a versatile building block for modified biomacromolecules and crosslinked delivery systems. With biocompatible degradation metabolites that can be effectively metabolized in biological environments, this polymer delivers consistent and reliable performance for conventional pharmaceutical and biomaterial research scenarios.
