  • Applications

    2,4-Dimethyl-4-nonanol (CAS 74356-31-3) is a branched tertiary aliphatic alcohol that is primarily used as an intermediate and as a fragrance-related ingredient; in the perfumery industry it may function as an odorant and a fixative, and in cosmetic and household product formulations it can serve as a solvent or processing aid. It can be converted to esters that serve as fragrance components or used as an intermediate in the synthesis of specialty chemicals for coatings, inks, and cleaners, subject to local regulations and formulation limits.
