Description

Cyclohexanone, 3-Methyl-5-(1-Methylethyl)-, (3S,5S)- (9Ci) is a high-purity, chiral ketone derivative of cyclohexanone, distinguished by its specific stereochemistry at the 3 and 5 positions. This compound matters as a valuable chiral building block and intermediate, offering precise molecular geometry critical for synthesizing complex, biologically active molecules. It is primarily needed by research and development chemists in the pharmaceutical and agrochemical industries for the creation of novel active ingredients, as well as by manufacturers of specialty fragrances and flavors.

Application

• Pharmaceutical Intermediate: Serves as a key chiral synthon in the asymmetric synthesis of active pharmaceutical ingredients (APIs), particularly for central nervous system (CNS) and anti-inflammatory drugs.
• Agrochemical Synthesis: Used in the research and production of advanced pesticides and herbicides where stereochemistry influences biological activity and environmental safety.
• Flavor & Fragrance Ingredient: Acts as a precursor for musky, woody, or amber notes in high-end perfumery and for creating complex flavor molecules.
• Organic Synthesis Research: A versatile starting material in academic and industrial R&D for exploring new catalytic asymmetric reactions and novel heterocyclic compounds.
• Liquid Crystal & Advanced Material Precursor: Potential use in the synthesis of chiral dopants for liquid crystal displays (LCDs) and other functional organic materials.

Quality Control

Our Cyclohexanone, 3-Methyl-5-(1-Methylethyl)-, (3S,5S)- (9Ci) is produced under strict quality management systems. Each batch undergoes rigorous analytical testing, including chiral purity assessment by HPLC, to ensure compliance with exacting R&D and production standards. Certificates of Analysis (COA) detailing identity, purity, enantiomeric excess, and impurity profiles are available upon request to support your regulatory and quality assurance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area at controlled room temperature (15-25°C). Due to its highly volatile nature, keep away from heat, sparks, and open flame. Ensure containers are kept upright and properly sealed when not in use to prevent evaporation and maintain purity.
