Description

Alanine, Propyl Ester (9Ci) is an alanine derivative where the carboxylic acid group is esterified with propanol. This modification enhances its lipophilicity, making it a valuable intermediate for the synthesis of more complex peptides, prodrugs, and specialty fine chemicals. It is primarily utilized by research institutions and industrial manufacturers in the pharmaceutical, agrochemical, and biotechnology sectors for developing novel compounds and active ingredients.

Application

• Pharmaceutical Intermediate: A key building block in the synthesis of peptide-based drugs, prodrugs, and active pharmaceutical ingredients (APIs).
• Biochemical Research: Used as a protected amino acid derivative in peptide coupling reactions and metabolic pathway studies.
• Agrochemical Synthesis: Serves as a precursor in the development of novel herbicides, fungicides, and plant growth regulators.
• Fine Chemical Production: Employed in the manufacture of chiral catalysts, ligands, and other specialty organic compounds.
• Flavor & Fragrance Industry: Potential use as an intermediate for creating specific amino acid-derived flavor compounds.
