  • Applications

    2-Norbornanol (CAS 1632-68-4) is primarily used as an intermediate in organic synthesis to access bicyclic norbornane derivatives, providing a versatile building block for downstream functionalization such as esters and ethers. It is commonly evaluated as a chiral starting material in pharmaceutical and fine-chemical development, and also serves as a platform chemical in polymer chemistry for norbornene-based monomers and crosslinkers used in plastics and coatings. In fragrance and flavor applications, it may be used as a scent intermediate or precursor to aroma compounds. Subject to local regulations and formulation limits.
