  • Applications

    Heptadecane, 5-methyl- (CAS 26730-95-0) is a branched C17 alkane used in industry primarily as a non-polar solvent or diluent in formulations, and as a hydrocarbon component in base oils and lubricants. It can be found in cleaning products and in coatings/inks formulations where low volatility and solvency for non-polar materials are desirable. It may serve as a processing aid or diluent in the production of polymers/plastics, helping to control viscosity and to carry additives. In analytical labs, it may be used as a reference or internal standard for hydrocarbon separations in gas chromatography. Its use is subject to local regulations and formulation limits.
