Description

Cyclohexanone, 5-Methyl-2-(1-Methylethyl)-, Oxime, (2R,5S)- (9Ci) is a high-purity, stereochemically defined oxime derivative of a substituted cyclohexanone. This compound is a valuable chiral intermediate and building block in advanced organic synthesis, prized for its defined stereochemistry which is critical for producing enantiomerically pure products. It is primarily utilized by research institutions and industrial R&D departments in the pharmaceutical, agrochemical, and fine chemical sectors for the development of novel active ingredients and complex molecules.

Application

• Pharmaceutical Intermediate: Serves as a key chiral synthon in the synthesis of complex drug candidates, particularly in routes requiring specific stereocenters.
• Agrochemical Research: Used in the development of novel pesticides and herbicides where the defined stereochemistry can influence biological activity.
• Fine Chemical Synthesis: Acts as a versatile building block for creating specialty chemicals, flavors, and fragrances.
• Asymmetric Catalysis: Employed as a ligand precursor or a substrate in catalytic reactions to induce chirality in target molecules.
• Academic & Industrial R&D: A critical reagent for methodological studies in organic chemistry and process development.
• Material Science Precursor: Potential use in synthesizing specialized polymers or functional materials with specific optical properties.
