Used primarily as a biomarker in geological and environmental studies to trace the presence of biological materials, especially in sediment and fossil analysis. Helps in identifying the origin of organic matter due to its stability and long-chain structure. Also employed in forensic science for source identification of organic residues. Serves as a reference standard in gas chromatography for analyzing alkanes in complex mixtures. Occasionally used in pesticide formulations as an inert ingredient to improve adhesion and dispersion.
