Used primarily in research settings as a reference standard in lipid analysis and metabolic studies. It helps in the identification and quantification of fatty acids in complex biological samples. Due to its long-chain saturated structure, it is also utilized in studying lipid metabolism, particularly in examining beta-oxidation pathways and fatty acid transport mechanisms. Occasionally employed in the synthesis of specialty esters and surfactants for laboratory use. Not commonly found in industrial applications due to limited availability and high cost.
