Description

(R)-2-Methylbutanol CAS NO 616-16-0 is a high-purity chiral alcohol, specifically the (R)-enantiomer of 2-methyl-1-butanol. This compound serves as a critical chiral building block and flavor/fragrance intermediate, valued for its defined stereochemistry and organoleptic properties. It is essential for manufacturers in the pharmaceutical, agrochemical, and specialty chemical industries requiring enantiomerically pure intermediates, as well as for producers of high-value flavors and fragrances.

Application

• Chiral Synthesis: A key starting material or resolving agent for the synthesis of enantiomerically pure pharmaceuticals and agrochemicals.
• Flavor & Fragrance Industry: Used as a component in creating complex, natural-tasting flavor profiles (e.g., fruity, whiskey notes) and in fine fragrance compositions.
• Advanced Material Production: Employed in the synthesis of chiral ligands for asymmetric catalysis and specialty polymers.
• Solvent for Specialty Applications: Acts as a solvent in high-value applications where its specific chirality and purity are advantageous.
• Research & Development: Serves as a standard or reagent in analytical chemistry and biochemical research focusing on stereoselective processes.

Quality Control

Our (R)-2-Methylbutanol is produced under strict quality management systems. Each batch is analyzed to ensure high enantiomeric excess (e.e.) and chemical purity, with specifications covering identity, assay, optical rotation, and impurity profiles. Certificates of Analysis (COA) detailing all test results are provided and can be tailored to meet specific customer or regulatory requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat sources and ignition points. Due to its highly volatile nature, ensure containers are kept tightly sealed when not in use to prevent evaporation and maintain purity. Recommended storage temperature is 2-8°C for long-term stability, though short-term storage at 15-25°C is acceptable.
