  • Applications

    Tokinolide B (CAS 112966-16-2) is a lactone-containing compound that can function as a synthetic intermediate in organic chemistry research. In industrial contexts, it may be evaluated as a chemical intermediate for the preparation of more complex molecules in pharmaceutical, agrochemical, and specialty chemical syntheses. Because of its lactone-derived aroma, it can be considered as a fragrance/odorant component for perfumery or cosmetic formulations, and it may also serve as an additive or building block in coatings, inks, or polymer-related applications. Any use would be subject to local regulations and formulation limits.
