Used primarily as a standard in analytical chemistry for hydrocarbon analysis, especially in gas chromatography and mass spectrometry. Serves as a reference compound in petroleum and environmental testing to identify long-chain alkanes. Also found in plant cuticles and insect waxes, it is studied in ecological and biological research for its role in water retention and pest resistance. Occasionally used in cosmetic and pharmaceutical formulations as an inert stabilizer or thickening agent due to its high molecular weight and low reactivity.
