  • Applications

    3-Ethyl-3-methylheptane (CAS 17302-01-1) is a branched decane isomer (C10) typically used as a nonpolar solvent and diluent in industrial applications, for example in coatings, cleaners, and adhesive or ink formulations. It can act as a component or diluent in lubricant bases and industrial fuel blends. In plastics and polymer processing, the compound may be employed as a processing solvent or thinning agent during formulation. Its nonfunctional hydrocarbon character allows it to serve as a reference material or calibration standard in analytical methods such as GC or GC-MS. Actual use depends on local regulations and formulation limits.
