Methaneselenol
Web1 sep. 1993 · Dimethyl selenone ((CH3)2SeO2) has been reported in the literature as a metabolite released by bacteria in contact with selenium metal or selenium salts. In this study, mass spectral, chromatographic, and boiling‐point data are presented that show that dimethyl selenone has been confused with dimethyl selenenyl sulfide (CH3SeSCH3). In … WebMethaneselenol is the organoselenium compound with the formula CH3SeH. It is the simplest selenol. A colorless gas, it is notorious for its foul odor.
