We developed a new assay method for fluoride anion (F(-)) a specific metabolite of sarin. Trimethyifluorosilane (TMFS) was derivatized from F(-) with trimethylsilanol, and TMFS was detected with a GC-flame ionization detector (FID) and capillary column system. The linear range

Genotoxicity studies on selected organosilicon compounds: in vivo assays.

A Isquith et al.

Food and chemical toxicology : an international journal published for the British Industrial Biological Research Association, 26(3), 263-266 (1988-03-01)

Six organosilicon compounds which had been found to have clastogenic activity in an in vitro battery of genotoxicity assays were evaluated in rat bone marrow cytogenetic assays for assessing clastogenicity in an in vivo system. None of the six compounds

Vibrational spectra of trimethylsilanol. The problem of the assignment of the SiOH group frequencies.

Igor S Ignatyev et al.

Spectrochimica acta. Part A, Molecular and biomolecular spectroscopy, 60(5), 1169-1178 (2004-04-16)

The assignment of the SiOH group vibrations of trimethylsilanol, which is still controversial, is proposed. This assignment is based on theoretical B3LYP force field scaled using the constants of the (CH3)3Si group optimized to fit experimental vibrational frequencies of (CH3)3SiF

Potassium trimethylsilanolate induced cleavage of 1,3-oxazolidin-2- and 5-ones, and application to the synthesis of (R)-salmeterol.

Diane M Coe et al.

Organic & biomolecular chemistry, 1(7), 1106-1111 (2003-08-21)

A convenient and efficient method for the cleavage of 1,3-oxazolidin-5-ones and 1,3-oxazolidin-2-ones utilising potassium trimethylsilanolate in tetrahydrofuran is described. The benzyloxycarbonyl-protecting group is readily removed under the reaction conditions, whereas the N-benzoyl group is stable. A synthesis of (R)-salmeterol exploiting

Gas chromatographic mass spectrometric detection of dihydroxy fatty acids preserved in the 'bound' phase of organic residues of archaeological pottery vessels.

Fabricio A Hansel et al.

Rapid communications in mass spectrometry : RCM, 25(13), 1893-1898 (2011-06-04)

A methodology is presented for the determination of dihydroxy fatty acids preserved in the 'bound' phase of organic residues preserved in archaeological potsherds. The method comprises saponification, esterification, silica gel column chromatographic fractionation, and analysis by gas chromatography/mass spectrometry. The
