  • Applications

    2H-Pyran, 2-butyl-3,6-dihydro-4,6-dimethyl- (CAS 24237-01-2) may be used as an intermediate in the synthesis of fragrance compounds and may serve as an odorant in perfumery and cosmetics. It may also function as a building block for fine chemicals used in pharmaceuticals and agrochemicals. In industrial manufacturing, it may be considered as a precursor for specialty polymers or coatings and inks, and could be explored for other material applications, subject to local regulations and formulation limits.
