Description

Sodium (S)-1-Phenylethanesulfinate is a high-purity chiral sulfinate salt, a key intermediate in asymmetric synthesis and pharmaceutical manufacturing. Its value lies in its role as a versatile chiral building block and ligand precursor, enabling the production of enantiomerically pure compounds. This product is essential for researchers and manufacturers in the pharmaceutical, agrochemical, and fine chemical industries who require high stereochemical control in their synthetic processes.

Application

• Pharmaceutical Intermediate: A critical chiral synthon in the synthesis of active pharmaceutical ingredients (APIs) requiring specific (S)-configuration.
• Asymmetric Synthesis: Used as a chiral auxiliary or precursor to chiral sulfoxides and other sulfur-containing ligands for catalytic reactions.
• Agrochemical Development: Employed in the research and production of enantiomerically pure herbicides, fungicides, and plant growth regulators.
• Fine Chemical Production: Serves as a building block for advanced materials, specialty chemicals, and flavor/fragrance compounds.
• Catalyst Ligand Preparation: A precursor for synthesizing chiral sulfoxide ligands used in transition metal catalysis.
• Academic & Industrial R&D: A valuable reagent for methodological development in organic and medicinal chemistry laboratories.

Quality Control

Our Sodium (S)-1-Phenylethanesulfinate is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including chiral purity analysis by HPLC, to ensure it meets the high standards required for advanced synthetic applications. Certificates of Analysis (COA) with detailed specifications for identity, assay, enantiomeric excess, and impurities are provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at a controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive) and should be handled under an inert atmosphere (e.g., nitrogen or argon) when possible to prevent oxidation and moisture uptake. Keep away from strong oxidizing agents.
