Description

Butanoic Acid, 3-Amino-, Methyl Ester, Hydrochloride, (R)- is a high-purity chiral building block and intermediate of significant importance in advanced organic synthesis. Its value lies in its enantiomeric purity, which is critical for producing optically active compounds with specific biological activities. This product is essential for research and development chemists and manufacturers in the pharmaceutical and agrochemical industries, particularly for the synthesis of active pharmaceutical ingredients (APIs) and fine chemicals where stereochemistry is paramount.

Application

• Pharmaceutical Intermediate: Key chiral synthon for the research and production of enantiomerically pure active pharmaceutical ingredients (APIs).
• Agrochemical Synthesis: Used in the development of chiral pesticides, herbicides, and plant growth regulators.
• Peptide Mimetics & Amino Acid Derivatives: Serves as a protected β-amino acid ester precursor for constructing complex peptide-like structures.
• Asymmetric Catalysis Research: A valuable substrate or ligand precursor in the development and study of new asymmetric synthetic methodologies.
• Fine Chemical Production: Employed in the multi-step synthesis of specialty chemicals, flavors, and fragrances requiring specific stereochemistry.
• Academic & Industrial R&D: A critical reagent for medicinal chemistry programs and process chemistry optimization in laboratory and pilot-scale settings.
