Used primarily as a reference standard in gas chromatography and mass spectrometry for identifying long-chain alkanes in complex mixtures. Commonly employed in environmental analysis to assess hydrocarbon contamination, especially in soil and water samples. Serves as a model compound in studies of wax formation and hydrocarbon biodegradation. Also utilized in the formulation of calibration mixtures for petroleum product analysis. Its high boiling point and stability make it suitable for simulating heavy fuel components in combustion and engine testing research.
