Used primarily as a component in fuel formulations, particularly in gasoline, due to its high octane rating and clean-burning properties. It serves as a reference standard in fuel testing to evaluate engine performance and knock resistance. Also found in some solvent blends for industrial cleaning and as a diluent in specialty applications where low reactivity and controlled evaporation rates are needed. Its branched alkane structure contributes to good thermal stability and compatibility with hydrocarbon-based systems.
