Description

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.

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)
