Used primarily as a reference standard in gas chromatography due to its well-defined boiling point and stability. Commonly employed in environmental testing to calibrate instruments for hydrocarbon analysis. Serves as a model compound in research on alkane biodegradation and microbial metabolism. Also utilized in fragrance formulations as a diluent or carrier for essential oils, providing slow evaporation properties. Found in some pesticide formulations as an inert ingredient to enhance penetration into plant tissues. Occasionally used in cosmetic products to impart a smooth texture, though less common due to availability of more suitable hydrocarbons.
