  • Applications

    2,9-Dimethylundecane, CAS 17301-26-7, is a branched long-chain hydrocarbon primarily used as a nonpolar solvent or diluent in industrial formulations. In coatings, inks, and adhesives, it can serve as a solvent for formulation thinning and to help dissolve resins and pigments. It is also used as a base oil or additive in lubricant formulations, contributing to flow properties and compatibility with other hydrocarbon components. The compound may be employed as a cleaning and degreasing solvent in industrial and consumer products. In polymer and plastics processing, it can be used as a processing solvent or diluent for certain polymers during casting or extrusion. Its actual use is subject to local regulations and formulation limits, and relies on properties such as volatility, viscosity, and compatibility with other ingredients.
