Description

(S,S)-2,3-Butanediol is a high-purity stereoisomer of 2,3-butanediol, a valuable chiral building block and intermediate. This optically active diol is significant for its role in asymmetric synthesis and as a precursor to fine chemicals and pharmaceuticals. It is primarily needed by research institutions and industrial manufacturers in the pharmaceutical, agrochemical, and specialty chemical sectors for developing chiral active ingredients and advanced materials.

Application

• Chiral Synthesis: A key starting material or intermediate in the asymmetric synthesis of pharmaceuticals, agrochemicals, and natural products.
• Pharmaceutical Intermediates: Used in the production of specific active pharmaceutical ingredients (APIs) requiring the (S,S) stereochemistry.
• Polymer & Resin Modification: Serves as a monomer or chain extender in the synthesis of specialized polyesters and polyurethanes, imparting specific physical properties.
• Flavor & Fragrance Industry: Acts as a precursor for certain chiral flavor and aroma compounds.
• Solvent & Carrier: Utilized as a high-boiling, biodegradable solvent for specialized applications in coatings and chemical reactions.
• Biochemical Research: Employed in enzymatic studies and as a standard in analytical chromatography for chiral separations.

Quality Control

Our (S,S)-2,3-Butanediol is produced under stringent quality management systems. Each batch undergoes comprehensive analytical testing, including chiral purity assay and impurity profiling, to ensure it meets exacting specifications for research and industrial use. A Certificate of Analysis (COA) detailing specific results for chiral purity, chemical purity, and relevant physical parameters is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive). Keep the container tightly sealed under an inert atmosphere (e.g., nitrogen) for long-term storage to prevent moisture absorption and potential oxidation.
