[Synthesis of 1-(difluoro-1,3,5-triazinyl)-2-methylisoindole as a fluorescent derivatization reagent and its reactivity for corticosteroids].
A fluorescence high-performance liquid chromatographic method for the determination of corticosteroids is described. Corticosteroids were labeled quantitatively by treatment with 1-(difluoro-1,3,5-triazinyl)-2-methylisoindole in an alkaline medium at room temperature for 10 s and the fluorescent adducts were eluted isocratically on a reversed-phase column by a mobile phase of aqueous methanol. The detection limit of cortisone was 3 pmol for an injection volume of 10 microliter.
