  • Applications

    (2S)-Hexan-2-ol (CAS 52019-78-0) is a chiral secondary alcohol widely used as an intermediate in organic synthesis. It serves as a building block for asymmetric transformations to access enantioenriched pharmaceuticals and other fine chemicals. In fragrance and flavor chemistry it is used as a precursor for aroma compounds, contributing to aroma profiles. In cosmetics and personal care it can function as a solvent or reactive intermediate for ester or ether derivatives. In cleaning and household formulations, it may act as a solvent or processing aid. In industrial manufacturing it serves as a solvent and a starting point for the preparation of various derivatives. It can also be used as a starting material for polymer and plastics-related chemistries through conversion to esters or other functional linkages. Subject to local regulations and formulation limits.
