  • Applications

    2-Methyloctacosane (CAS 1560-98-1) is a high-molecular-weight branched alkane that is mainly handled as a nonpolar hydrocarbon in formulations; in real-world applications it may be used as a high-boiling diluent/solvent and processing aid in industrial manufacturing, as a waxy component or lubricant in coatings, paints, and plastics processing, and as an emollient or carrier in cosmetics/personal care formulations. It can also serve as a reference or calibration standard for GC analysis of long-chain hydrocarbons. Its use is typically subject to local regulations and formulation limits.
