General Description

(S)-4-Methyl-2,5-oxazolidonedione, also known as L-Alanine NCA, is the N-carboxyanhydride of L-alanine, used as a high-purity monomer for ring-opening polymerization.

Mechanism of Action

It serves as an activated monomer for the synthesis of poly-L-alanine. The polymerization process is driven by the loss of CO2, providing a clean route to polypeptides with low polydispersity.

Application

It is utilized in the fabrication of biodegradable polymers, synthetic protein fibers, and controlled-release pharmaceutical formulations.
