PLGA-diamine

Price range: $260.00 through $960.00

PLGA-diamine is an amine-functionalized biodegradable copolymer composed of poly(D,L-lactide-co-glycolide) (PLGA) terminated with primary amine groups at both chain ends. The terminal amine groups provide versatile reactive sites for polymer conjugation, PEGylation, peptide attachment, drug coupling, and biomaterials development. PLGA-diamine is widely used in drug delivery, tissue engineering, nanoparticle fabrication, and biomedical research.

Description

General Description

PLGA-diamine is a biodegradable polyester synthesized from D,L-lactide and glycolide and functionalized with primary amine groups at both termini. The PLGA backbone provides excellent biodegradability and biocompatibility, while the terminal amine groups enable efficient conjugation with activated esters, carboxylic acids, aldehydes, isocyanates, and other amine-reactive compounds.

The reactive amine functionality makes PLGA-diamine an important intermediate for the synthesis of functional block copolymers, targeted drug delivery systems, polymer-drug conjugates, nanoparticles, and biomaterials. The polymer combines the proven performance of PLGA with versatile amine chemistry for a wide range of biomedical applications.
