Methyl arachidate is commonly used as a standard in gas chromatography for the identification and quantification of fatty acid methyl esters (FAMEs). It serves as a reference compound in analytical studies, particularly in lipid analysis, to ensure accurate measurement and comparison of fatty acid profiles in various biological and industrial samples. Additionally, it is utilized in research involving the synthesis and characterization of lipid-based materials, contributing to the development of biofuels, cosmetics, and pharmaceuticals. Its role in calibrating instruments and validating methods makes it a critical component in laboratories focused on lipid chemistry and related fields.
