Description

1,2,3-Propanetriol, 1,2-Diacetate, (S)- is a chiral diacetate derivative of glycerol, a key intermediate in fine chemical synthesis. Its defined stereochemistry at the (S)-configured carbon center makes it a valuable building block for producing enantiomerically pure pharmaceuticals and advanced materials. This high-purity chiral synthon is essential for research and manufacturing in the pharmaceutical, agrochemical, and specialty chemical industries. The compound is identified by CAS No. 127179-48-0.

Application

• Chiral Pharmaceutical Intermediate: A critical precursor in the asymmetric synthesis of active pharmaceutical ingredients (APIs), particularly for cardiovascular and central nervous system drugs.
• Agrochemical Synthesis: Used in the production of enantiomerically pure herbicides, fungicides, and plant growth regulators for enhanced efficacy.
• Liquid Crystal & Polymer Chemistry: Serves as a chiral dopant or monomer for synthesizing advanced polymers and liquid crystal displays (LCDs) with specific optical properties.
• Flavor & Fragrance Industry: Acts as a chiral intermediate for creating stereochemically defined aroma chemicals and flavor compounds.
• Biocatalyst & Enzyme Studies: Employed as a substrate or standard in enzymatic resolution studies and biocatalysis research.
• Academic & R&D Laboratories: A high-value reagent for methodological development in organic synthesis and stereochemistry research.

Quality Control

Our 1,2,3-Propanetriol, 1,2-Diacetate, (S)- is manufactured under strict quality management systems. Each batch is subjected to rigorous analytical testing, including chiral purity analysis by HPLC, to ensure compliance with exacting standards for enantiomeric excess (ee) and chemical purity. Certificates of Analysis (COA) detailing identity, assay, chiral purity, and impurity profiles are provided with every shipment to guarantee traceability and batch-to-batch consistency for your critical applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at controlled room temperature (15-25°C). The product is moisture-sensitive; keep the container tightly sealed under an inert atmosphere (e.g., nitrogen) for long-term storage to prevent hydrolysis. Keep away from strong oxidizing agents.
