Used primarily as a component in research and development of high-octane fuel blends due to its branched hydrocarbon structure, which helps reduce engine knocking. It serves as a model compound in combustion studies to evaluate ignition behavior and emission profiles in internal combustion engines. Also utilized in analytical chemistry as a reference standard in gas chromatography for identifying unknown hydrocarbons in complex mixtures. Its stability and volatility make it suitable for simulating fuel performance under controlled conditions.
