General description

Hexanoyl-L-carnitine belongs to the class of straight-chain acylcarnitines, which are important biomarkers in the diagnosis of carnitine deficiency.

Application

Hexanoyl-L-carnitine may be used as an analytical reference standard for the quantification of the analyte in dried blood spots using high-performance liquid chromatography coupled to electrospray ionization tandem mass spectrometry (HPLC-ESI-MS/MS). Hexanoyl-L-carnitine may also be used as an analytical standard for the separation and identification of underivatized hexanoyl-L-carnitine in human plasma samples using HPLC-MS/MS.

Electrospray ionization-tandem mass spectrometry (ESI-MS/MS) is increasingly used in newborn screening programs. Acylcarnitine profiles from dried blood spots (DBS) are used to detect fatty acid oxidation disorders, carnitine cycle disorders, and organic acidurias. Stored dried blood is also a valuable

A simple HPLC-MS/MS method has been established to separate and identify underivatized acylcarnitine isomers. Human plasma samples were deproteinized and concentrated. Acylcarnitines were separated on a reverse phase column and detected with triple quadrupole linear ion trap mass spectrometry. Deuterium-labeled
