Description

(S)-Methyl 3-((S)-1-Phenylethylamino)Butanoate is a high-purity chiral intermediate of significant importance in asymmetric synthesis. Its value lies in its role as a key building block for the production of advanced pharmaceutical compounds, particularly those requiring specific stereochemistry. This product is essential for research institutions and manufacturers in the pharmaceutical, agrochemical, and fine chemical industries who are developing or producing enantiomerically pure active ingredients.

Application

• Pharmaceutical Intermediate: A critical chiral synthon in the synthesis of enantiomerically pure active pharmaceutical ingredients (APIs), especially for cardiovascular and central nervous system drugs.
• Asymmetric Synthesis: Used as a chiral auxiliary or building block in stereoselective reactions, including Michael additions and alkylations, to construct complex molecular architectures.
• Agrochemical Research: Serves as a precursor in the development of chiral pesticides and herbicides where specific isomer activity is required.
• Fine Chemical Production: Employed in the manufacture of specialty chemicals, flavors, and fragrances that demand high enantiomeric purity.
• Catalyst Ligand Precursor: Can be utilized in the development of chiral ligands for transition metal catalysis.
• Academic & R&D: A valuable compound for methodological research in organic chemistry and process development within university and corporate laboratories.

Quality Control

Our (S)-Methyl 3-((S)-1-Phenylethylamino)Butanoate is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including chiral HPLC for enantiomeric excess (ee) and standard purity assays, to ensure it meets the high standards required for pharmaceutical R&D and production. Certificates of Analysis (COA) detailing identity, purity, chiral purity, and impurity profiles are available for every lot upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen) after opening to prevent degradation. Keep away from strong bases and incompatible materials.
