| Application: | Methyl stearate has been used as a reference standard • in gas chromatography (GC) to evaluate the absolute amount of methyl stearate among the fatty acid methyl esters of biodiesel • to evaluate the intramuscular fatty acid profile of fresh lamb meat in GC • to qualitatively analyse the transesterification reaction products by thin layer chromatography |
| General description: | Methyl stearate or methyl octadecanoic acid is a saturated methyl ester and a representative key molecule of biodiesel fatty acid methyl esters (FAMEs) produced from vegetable oils. Methyl stearate occurs naturally in clove oil. |
