Description

(R,R)-2,3-Butanediol is a high-purity stereoisomer of 2,3-butanediol, a valuable chiral building block and intermediate. This specific enantiomer is critical for synthesizing optically active compounds where precise stereochemistry dictates function and performance. It is essential for research and production in the pharmaceutical, agrochemical, and specialty chemical industries, serving as a precursor for chiral ligands, pharmaceuticals, and fine chemicals.

Application

• Chiral Synthesis: As a key starting material or intermediate in the asymmetric synthesis of active pharmaceutical ingredients (APIs) and agrochemicals.
• Pharmaceutical Intermediates: Used in the production of chiral drugs, where the (R,R) configuration is required for specific biological activity.
• Ligand and Catalyst Preparation: Serves as a backbone for synthesizing chiral ligands used in homogeneous catalysis (e.g., for hydrogenation or cross-coupling reactions).
• Fine Chemical Production: A building block for flavors, fragrances, and other high-value specialty chemicals requiring defined stereochemistry.
• Biochemical Research: Used as a standard or reagent in enzymatic studies and metabolic pathway analysis.
• Polymer Chemistry: Potential monomer for creating polymers with specific stereoregular structures and properties.

Quality Control

Our (R,R)-2,3-Butanediol is produced and tested under a strict quality management system. Each batch is analyzed to ensure high chemical and enantiomeric purity, meeting the stringent requirements for chiral intermediates. A comprehensive Certificate of Analysis (COA) detailing identity, assay, enantiomeric excess, and impurity profiles 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) and should be handled under an inert atmosphere (e.g., nitrogen or argon) to prevent oxidation and moisture uptake after opening.
