9,12,15-Octadecatrienoic acid, methyl ester, commonly known as methyl linolenate, is a fatty acid methyl ester characterized by its three double bonds, indicating a polyunsaturated structure. This compound is particularly noted for its applications in analytical chemistry, where it is often used as a standard in gas chromatography and high-performance liquid chromatography for the analysis of fatty acid methyl ester isomers[1].The molecular formula for methyl linolenate is C19H32O2, and it has a molecular weight of approximately 292.4562 g/mol. This substance is useful in various studies due to its significant chemical and physical properties, including its melting and boiling points, and its behavior in different phases which are crucial for understanding its reactivity and stability under various conditions [2].Additionally, methyl linolenate serves as an example within the broader category of unsaturated fatty acids, which are important in many biological and environmental contexts. This includes potential roles in the biodegradation processes and its use in ecological studies to assess environmental impacts[1].
