N-Carboxyalanine Anhydride (CAT: R040963) is a cyclic amino acid derivative widely used as a monomer in the synthesis of polypeptides via ring-opening polymerization. Derived from alanine, this N-carboxyanhydride offers a reactive yet controllable route to preparing homopolypeptides and block copolymers with defined chain lengths and stereochemistry. It is a critical tool in developing biomaterials, drug delivery systems, and peptide-based nanostructures. NCA-Ala enables precise peptide synthesis under mild conditions and is valued for its high purity and reproducibility.
