Used primarily as a biomarker in geological and environmental studies to identify plant-derived organic matter in sediments and soils. Its presence indicates contributions from higher plants, especially in paleoenvironmental reconstructions. Also employed in forensic science to analyze petroleum products and distinguish biological sources in sample testing. Serves as a reference standard in gas chromatography due to its stable hydrocarbon structure and defined retention time. Occasionally used in the formulation of specialty waxes for coatings and polishes where high molecular weight alkanes are required.
