  • Applications

    2-(4-Methyl-5-thiazolyl)ethyl decanoate is commonly used as an odorant and fragrance fixative in perfumery and cosmetic formulations, providing extended scent release. It may also function as an aroma chemical in flavor formulations under controlled use. The compound can act as an intermediate in fragrance synthesis, aiding the development of thiazole-containing scent motifs. Additionally, it finds applications in household products such as cleaners and air fresheners to impart specific fragrance notes, and in industrial manufacturing as a fragrance component for coatings and inks. Its use is subject to local regulations and formulation limits.
