  • Applications

    Ethyl 3-hydroxyoctanoate (CAS 7367-90-0) is used primarily as an intermediate in organic synthesis and as a fragrance/odorant ingredient in perfumery and personal care. It can serve as a building block for hydroxy-functional esters and hydroxy-terminated polyesters, enabling the production of specialty polymers used in coatings, plastics, and adhesives. The compound may also appear in cosmetic formulations as a fragrance component or processing aid, and it can be evaluated as a solvent or processing additive in cleaning and industrial formulations, subject to local regulations and formulation limits.
