Rotten cabbage

Colorless gas or water-white liquid with a disagreeable odor like garlic or rotten cabbage that is detectable at 0.0021 ppm. This material is hazardous through inhalation. 

Colorless gas with a garlic-like or rotten cabbage odor. An experimentally determined odor threshold concentration of 2.1 ppbv was reported by Leonardos et al. (1969). A detection odor threshold concentration of 81 pg/m (41 ppbv) was determined by Katz and Talbert (1930). 

Physical Form. Flammable gas liquefying at 6°C odor of rotten cabbage... 

Bis(trimethylsilyl) selenide (mp -7°, bp 58-59°/ll torr)14 and bis(trimethyl-silyl) telluride (mp 13.5°, bp 74°/11 torr)14 are liquids of low volatility with revolting and persistent odors resembling garlic and rotten cabbage. They exhibit first-order H nmr spectra 2,3 [(CH3)3Si]2Se 5(CH3) 0.43 ppm,/(H—13C)... 

This is used as a solvent for the percutaneous administration of certain drugs in die horse. It imparts an odour of rotten cabbage, probably as the result of sulphide formation. 

Many individual compounds. Colourless liquids rotten cabbage/garlic/skunk-like smell. Used as a stench gas odorant and as the starting point for synthesis of plastics, insecticides, etc. Irritants. Large exposure drowsiness, chemical pneumonitis. 

The odor of rotten cabbage is very diffusive and objectionable (Arctander, 1967). On the other hand, despite these characteristics and certainly thanks to its originality, this mercaptan gives one of the most intense noted to roasted coffee. The threshold concentration in water varies between 0.02 ppb (Guadagni et al., 1963a), and 2.1 ppb (quoted by Persson and von Sydow, 1973). 

F. Functional groups containing sulfuF 1 —C—SH 1 thiol (also called mercaptan) CH3SH methanethiol, has the odor of rotten cabbage... 

Methyl mercaptan 1064 S I 5/23 0.002 ppm rotten cabbage (at 1 ppm odour fatigue begins)...
