Used as a reference standard in gas chromatography due to its stable and predictable retention time. Commonly employed in environmental testing to analyze hydrocarbon pollutants in soil and water samples. Serves as a component in calibration mixtures for analytical instruments. Found in some fragrance formulations as a solvent or diluent. Used in research settings to study alkane biodegradation and microbial metabolism. Also utilized in the preparation of certain specialty lubricants and coatings where a long-chain alkane is required.
