Description

2,2,5,7,8-Pentamethyl-6-chromanol is the suitable reagent used for the quantitative analysis of α-tocopherol by plasma-based gas chromatography/tandem mass spectrometry (GC/MS/MS) using a tabletop quadrupole ion trap mass spectrometer.It may be employed as α-tocopherol model compound and on oxidation byt-butyl hydroperoxide in chloroform, in the presence of alcohol, affords 5-alkoxymethyl-2,2,7,8-tetramethyl-6-chromanol.It may be used as internal standard for the determination of α- and γ-tocopherol in the rabbit serum and liver by HPLC.
