Negative ion mass spectrometry of benzophenones, the acid hydrolysis products of benzodiazepines: Negative ion mass spectrometry of benzophenones, the acid hydrolysis products of benzodiazepines. Suzuki, Osamu; Hattori, Hideki; Takahashi, Toshie; Brandenberger, Hans (Dep. Legal Med., Equip. Cent., Hamamatsu, Japan). Iyo Masu Kenkyukai Koenshu, 11, 173-6 (Japanese) 1986. CODEN: KIMKDN. DOCUMENT TYPE: Journal CA Section: 1 (Pharmacology) Section cross-reference(s): 73 Pos. electron impact (EI), pos. chem. ionization (CI), and neg. CI mass spectra of 14 benzophenones were recorded. In the pos. EI mode, intense mol. peaks appeared for most compds.; some other peaks due to splitting at both sides of the carbonyl group also appeared. In the pos. CI mode, (M + 1)+ quasi-mol. ions together with (M + C2H5)+ peaks were obsd. for all compds.; some fragment peaks were common to those in the pos.Several substances like 1775-95-7 may be metioned in this study. EI model. In the neg. CI mode, the spectra were much simpler than those in the pos. EI or CI mode. In the 1 Torr neg. CI mode, some spectra showed only single mol. anions; in the 0.01 Torr neg. CI mode, halogen or nitro peaks appeared in addn. to the mol. anions. An extn. procedure for benzophenones from human urine and plasma after heating in strong acid, and their sepn. by gas chromatog. (GC) were also presented to serve for their actual identification by GC/mass spectrometry. .
