Methyl arachidate is primarily used as a reference standard in gas chromatography for the analysis and identification of fatty acid methyl esters (FAMEs). It plays a crucial role in lipid research, helping scientists study the composition and structure of fats and oils. Additionally, it serves as a model compound in the synthesis of more complex lipids and esters, aiding in the development of new materials and chemicals. In industrial applications, it is utilized in the formulation of lubricants and coatings, where its properties contribute to enhanced performance and stability.
