Dichlorotetrafluoroacetone as a derivatisation reagent in the analysis of mandelic acids in human urine.
Dichlorotetrafluoroacetone has been used to prepare 4-substituted 2-bis (chlorodifluoromethyl)-1,3-dioxolan-5-one derivatives of mandelic acids which were found to be suitable for the analysis of these compounds by gas chromatography-negative-ion chemical ionisation mass spectrometry (GC-NICIMS). The high specificity of the derivatising agent facilitates the identification and quantitation of small amounts of mandelic acids in complex biological matrices. The derivatisation procedure was used to determine the concentrations of m- and p-hydroxymandelic acids and vanillylmandelic acid in to the urine of normal subjects. The method may also have application in the determination of isomeric phenylethylene glycols, the corresponding products of reductive metabolism of biogenic amines.
