Used primarily as a standard in gas chromatography and mass spectrometry for hydrocarbon analysis. Serves as a model compound in studies of alkane behavior, including crystallization, phase transitions, and thermal properties. Found in some cosmetic and skincare formulations as an emollient or thickening agent due to its waxy consistency. Also investigated in phase-change materials for thermal energy storage because of its high melting point and ability to store heat during solid-liquid transitions. Present in petroleum products and used in environmental studies to track hydrocarbon pollution and biodegradation processes.
