Description
General Description
PCL Acid (PCL-COOH) is a carboxyl-terminated poly(ε-caprolactone) containing a reactive carboxylic acid group at the polymer chain end.
Poly(ε-caprolactone) (PCL) is a biodegradable, hydrophobic aliphatic polyester widely used in drug delivery, tissue engineering, regenerative medicine, and biomaterials research. Its relatively slow hydrolytic degradation and good compatibility with many hydrophobic compounds make PCL particularly useful for sustained drug delivery and long-term biodegradable materials.
The terminal carboxylic acid (–COOH) provides a convenient site for further chemical modification. The carboxyl group can be activated using carbodiimide coupling reagents such as EDC/NHS and subsequently reacted with primary amines to form stable amide bonds.
PCL-COOH can therefore be used to prepare functional PCL derivatives, polymer-drug conjugates, polymer-peptide conjugates, block copolymers, functionalized nanoparticles, surface coatings, and other advanced biomaterials.
