  • Applications

    Exo-2-norbornyl formate (CAS 41498-71-9) is an ester of formic acid and the exo-2-norbornanol alcohol. In practice, it is typically viewed as an organic synthesis intermediate and may be explored for applications related to fragrance and cosmetics/personal care due to its characteristic odor. It can also function as a solvent or diluent in certain industrial formulations, including coatings and inks, and may serve as a building block or additive in polymer or plastics formulations. Use, where permitted, is subject to local regulations and formulation limits.
