General Description
PCL-Amine (PCL-NH₂), also known as amine-functionalized poly(ε-caprolactone) or amino-PCL, is a biodegradable polyester containing a terminal primary amine (NH₂) functional group.
Poly(ε-caprolactone) (PCL) is a hydrophobic, biodegradable aliphatic polyester widely used in biomaterials and drug delivery research. Introduction of a terminal amine provides a reactive site for further chemical modification while retaining the hydrophobic and biodegradable characteristics of the PCL chain.
The primary amine can react with NHS esters, activated carboxylic acids, aldehydes, isocyanates, and other amine-reactive compounds. PCL-NH₂ can therefore be used as a building block for preparing functional polymers, polymer-drug conjugates, ligand-functionalized materials, and amphiphilic block copolymers.
