Used primarily as a high-purity reference standard in gas chromatography and mass spectrometry for identifying and quantifying hydrocarbons in complex mixtures. Its well-defined structure and stability make it suitable for calibration in petroleum and fuel analysis. Also employed in research settings to study branched alkane behavior under various thermal and catalytic conditions. Due to its high degree of branching, it serves as a model compound in combustion studies, helping evaluate ignition characteristics and octane performance in spark-ignition engines.
