  • Applications

    7-Methylpentadecane (CAS 6165-40-8) is a branched long-chain alkane that primarily serves as a non-polar hydrocarbon carrier in formulations. In industry, it is commonly used as a solvent or diluent for coatings, inks, and plastics processing, providing a low-polarity carrier with favorable volatility. It can function as a basestock or processing fluid in synthetic lubricants and lubricant blends where low water miscibility is important. It is also used as a reference hydrocarbon and intermediate in hydrocarbon synthesis and formulation development. In cosmetics and fragrance, it may be used as a diluent or carrier for fragrance compounds, subject to formulation constraints. Additionally, it can appear as a hydrocarbon solvent component in cleaning and maintenance formulations.
