Application

This analytical standard can also be used as follows:
  • Comparative analysis of gas chromatography-combustion-mass spectrometry and gas chromatography-flame ionization detector methods for the determination of fatty acid methyl esters (FAMEs) in biodiesel samples
  • Gas chromatography-tandem differential mobility spectrometry (DMS) based separation and quantification of 16 methyl- and ethyl- fatty acid esters from biodiesel samples
  • Analysis of coffee oil and residue obtained from roasted coffee beans to determine the composition of 11 fatty acids following their methyl esterification by gas chromatography coupled with a flame ionization detector (GC-FID)
  • Separation and quantification of eight fatty acids after their derivatization to methyl esters in the oil extracted from the leaves of Abutilon hirtum (Lam.) by GC-MS
  • Gas chromatography-mass spectrometry (GC-MS) based microanalysis of orchid seeds using direct transesterification for the determination of fatty acid methyl esters (FAMEs)

General description

Methyl arachidate belongs to the group of fatty acid methyl esters (FAMEs), obtained on the transesterification of arachidic acid with methanol. It is a wax-like solid which is soluble in alcohol and ether and insoluble in water.
