Ishibashi, Masataka published the artcileDiethylhydrogensilyl-cyclic diethylsilylene derivatives in the gas chromatography-mass spectrometry of hydroxylated steroids. IV. Hydrocortisone, Related Products of catalysis-chemistry, the publication is Journal of Chromatography (1987), 197-206, database is CAplus.
The 3,20-bismethyloxime-11-diethylhydrogensilyl-17,21-cyclic diethylsilylene derivative of hydrocortisone (HC) was obtained by treating HC with O-methylhydroxylamine-HCl and then with N,O-bis(diethylhydrogensilyl)trifluoroacetamide. This derivative gave a single peak without resolution of its structural isomers. The electron-impact mass spectrum of the HC derivative was characterized by the appearance of an intense mol. ion peak and principal ion peak of [M – OCH3]+ at m/z 559. The detection limit was 10 pg with a signal-to-noise ratio of >10 when gas chromatog. (GC)-selected ion monitoring was carried out at the mol. ion of m/z 590. On the other hand, GC-metastable peak monitoring, based on the metastable peak corresponding to the transition ions from m/z 590 to 559, showed a detection limit of ?10 pg with a signal-to-noise ratio of >5.
