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 studies of long-chain alkanes, including combustion behavior and degradation in soil and water. Also utilized in the formulation of certain specialty lubricants and waxes where a high molecular weight hydrocarbon is required. Occasionally found in cosmetic and personal care products as an inert ingredient to modify texture and consistency.
