PLGA-di-amine, MW 10K

PLGA-di-amine, MW 10K is a medium-molecular-weight linear biodegradable copolymer dual-terminated with reactive primary amine groups. Synthesized from D,L-lactide and glycolide monomers, the polymer covers all mainstream LA/GA ratios and supports fully customized proportions to adapt to diverse biomedical design requirements. Balancing moderate molecular chain length and stable chemical activity, the 10K grade avoids the excessively fast degradation of low-molecular polymers while retaining efficient amine-group reactivity for common biomedical modifications. The bifunctional terminal -NH₂ groups can stably react with carboxylic acid, NHS ester and other active groups, enabling reliable preparation of amphiphilic block copolymers, crosslinked hydrogel systems, and surface-functionalized drug delivery carriers. With biologically safe and metabolizable degradation products, this versatile PLGA-amine derivative exhibits steady comprehensive performance, making it the most widely applicable grade for conventional bioconjugation, nanoparticle modification and controlled-release material construction.
