  • Applications

    9-Methyldecanoic acid (CAS 1119-63-7) is a branched C10 fatty acid that serves as a useful chemical intermediate and feedstock in several industries. It may be used as a precursor for the synthesis of fragrance esters and other specialty aroma compounds in perfumery and flavor applications; as a building block for cosmetic and personal-care ingredients (emollients and surfactant precursors) and for polymer-related formulations; as a component or modifier in lubricant and plasticizer systems in industrial manufacturing; and as a precursor for coatings and inks to tailor crystallinity and compatibility. Its use is typically formulation- and regulation-dependent.
