Description

Asparagine,Ethylester(9Ci) CAS NO 764724-22-3 is a protected derivative of the amino acid L-asparagine, where the carboxylic acid group is esterified with ethanol. This modification is crucial for enhancing the molecule's stability and solubility in organic solvents, making it a valuable building block in synthetic organic chemistry. It is primarily utilized by researchers and manufacturers in the pharmaceutical and biotechnology sectors for the synthesis of peptides, peptidomimetics, and other bioactive compounds.

Application

• Pharmaceutical Intermediate: A key protected amino acid derivative for the synthesis of complex peptide-based drugs and active pharmaceutical ingredients (APIs).
• Peptide Synthesis: Serves as a crucial building block in solid-phase and solution-phase peptide synthesis (SPPS) to prevent unwanted side reactions.
• Biochemical Research: Used in academic and industrial R&D for studying enzyme mechanisms, protein structure, and metabolic pathways.
• Prodrug Development: Employed in the design of prodrugs where the ethyl ester moiety can be cleaved enzymatically in vivo.
• Fine Chemical Synthesis: Acts as a chiral synthon for the asymmetric synthesis of more complex natural products and specialty chemicals.
