Methyl linolenate, with the molecular formula C19H32O2, is a polyunsaturated fatty acid ester derived from alpha-linolenic acid. This compound is primarily used in scientific studies related to the oxidation and peroxidation of unsaturated fatty acids. Its properties make it a subject of interest in research concerning the prevention of these chemical processes. Moreover, methyl linolenate has been explored for potential applications in dermatology, specifically as a skin whitening agent with anti-melanogenesis activity[1,2]. The chemical exhibits a melting point of -57°C and a boiling point of 182°C at 3 mmHg. It is stored at temperatures between 2-8°C to maintain stability and prevent degradation. The compound is typically handled in liquid form and has a refractive index of n20/D 1.470. These physicochemical properties are crucial for its handling and application in various research settings [3,4].
