General description

Fusaric acid is a novel proton-affinitive derivatizing agent, having an ionization moiety and a hydrophobic moiety. It is commonly used for the derivatization of alcohols and phenols, by liquid chromatography coupled with electrospray ionization tandem mass spectrometry (LC/ESI-MS/MS).

Application

Fusaric acid may be used as a derivatizing reagent for the quantification of hydroxysteroids and dehydroepiandrosterone (DHEA) and sulfated DHEA in biological samples using liquid chromatography electrospray-ionization-tandem mass spectrometry (LC/ESI-MS/MS) technique.

A highly sensitive derivatization method for liquid chromatography (LC)-electrospray ionization (ESI) tandem mass spectrometry of dehydroepiandrosterone (DHEA), testosterone (T), pregnenolone (P5), and 17alpha-OH-pregnenolone (17-OHP5) was developed based on the use of fusaric acid as a reagent. DHEA, P5, and 17-OHP5
