  • Applications

    (+)-3-Methylcyclohexanone, CAS number: 13368-65-5, is commonly used as an organic intermediate for the synthesis of chiral compounds in pharmaceuticals and agrochemicals, serving as a precursor to enantioenriched amines or alcohols. It also functions as a building block in the fragrance and flavor industry, supporting fragrance formulations and flavor synthesis. In research and development, it is used as a scaffold for asymmetric reactions and for designing chiral catalysts or ligands. Additionally, it may be used as a solvent or reaction medium for certain steps in organic synthesis. These applications are subject to local regulations and formulation limits.
