  • Applications

    2H-Pyran, tetrahydro-4-methyl-2-(2-methylpropyl)- (CAS number: 13477-62-8) is used as a useful intermediate in organic synthesis and is often evaluated for fragrance-related applications in perfumery, where it can function as an odorant or fragrance fixative. In cosmetics and personal care, it may be used as a scent component; in the flavor industry, it may be evaluated for aroma-related applications; in household products, it can be used to impart fragrance in cleaners or air fresheners. In industrial manufacturing, it is typically used as an intermediate for the synthesis of other compounds or as a solvent/precursor for polymer-related chemistries. It may also be explored as a building block for specialty polymers or plastics, subject to formulation limits and local regulations.
