α-benzylcarboxylate-ε-caprolactone

Description

General Description

BCL (α-Benzyl Carboxylate-ε-Caprolactone) is a modified caprolactone monomer designed to introduce reactive pendant functional groups into biodegradable polyester backbones. The benzyl-protected carboxylate group remains stable during ring-opening polymerization while allowing subsequent deprotection to generate carboxylic acid-functionalized polymers.

BCL is frequently copolymerized with ε-caprolactone, lactide, glycolide, and PEG-containing initiators to produce functional biodegradable polymers with tunable physicochemical properties. Following deprotection, the resulting polymers provide reactive carboxyl groups for conjugation with peptides, proteins, drugs, targeting ligands, and other biomolecules. BCL has become an important building block for drug delivery systems, polymer therapeutics, tissue engineering scaffolds, and nanomedicine applications.
