  • Applications

    Dodecan-2-ol, CAS 10203-28-8, primarily serves as an intermediate and building block in organic synthesis, notably for producing dodecyl esters and wax-like components used in lubricants and personal care formulations; it is a fatty alcohol precursor for surfactants and related derivatives in cosmetics and household care; in perfumery, it can act as a solvent or carrier for fragrance materials; in coatings, inks, and household products it is used as a solvent or co-surfactant; in polymers and plastics processing it can function as a lubricant additive or plasticizer precursor.
