Description

(S)-Propyl 2-Aminopropanoate Hydrochloride is a high-purity chiral building block and salt form of an amino acid ester, essential for the synthesis of optically active compounds. This material is critical for ensuring enantiomeric purity and process consistency in advanced pharmaceutical and fine chemical research. It is primarily utilized by R&D chemists and process development scientists in the pharmaceutical, agrochemical, and specialty chemical industries for applications requiring the (S)-alanine moiety.

Application

• Pharmaceutical Intermediate: Key chiral synthon for the development of active pharmaceutical ingredients (APIs), particularly in protease inhibitors and other small molecule therapeutics.
• Peptide Synthesis: Used as a protected amino acid derivative in solid-phase and solution-phase peptide chemistry to introduce the (S)-alanine residue.
• Asymmetric Catalysis Research: Serves as a precursor or ligand in the development of chiral catalysts and auxiliaries.
• Agrochemical Synthesis: Building block for creating enantiomerically pure herbicides, fungicides, and plant growth regulators.
• Biochemical Research: Substrate or inhibitor in enzymatic studies and metabolic pathway investigations.
• Flavor & Fragrance Industry: Potential intermediate for the synthesis of specific, high-value flavor compounds.
