Description

Cyclohexanone, 5-Methyl-2-(1-Methylethyl)-, (2R)- (9Ci) is a high-purity, chiral terpenoid derivative of significant interest in advanced organic synthesis. This compound matters as a key chiral building block and intermediate, offering precise stereochemical control for the production of complex molecules. It is needed by R&D chemists and process development teams in the pharmaceutical, agrochemical, and fine chemical industries for applications in asymmetric synthesis and fragrance development.

Application

• Pharmaceutical Intermediate: Serves as a chiral synthon in the asymmetric synthesis of active pharmaceutical ingredients (APIs), particularly for terpene-based drug candidates.
• Agrochemical Synthesis: Used in the research and development of chiral pesticides and herbicides where specific stereochemistry is crucial for biological activity.
• Fine Chemical Production: Acts as a precursor for the synthesis of complex natural products, flavors, and fragrances requiring the (2R) enantiomer.
• Asymmetric Catalysis Research: Employed as a standard or substrate in academic and industrial research to develop and test new chiral catalysts and methodologies.
• Fragrance and Flavor Ingredient: Utilized as an intermediate in the creation of specific, high-value aroma chemicals for premium perfumery.
