    Methanethiol (also known as methyl mercaptan) is a colorless gas with a smell like rotten cabbage. It is a natural substance found in the blood and brain of humans and other animal as well as plant tissues. It is disposed of through animal feces. It occurs naturally in certain foods, such as some nuts and cheese. It is also one of the main chemicals responsible for bad breath and the smell of flatus. Methanethiol is mainly used to produce methionine, which is used as a dietary component in poultry and animal feed. Methanethiol is also used in the plastics industry and as a precursor in the manufacture of pesticides. It is also released as a decay product of wood in pulp mills. Due to the extremely low odor threshold of thiols in general, they may be added to otherwise odorless gases such as natural gas, enabling people to detect leaks by smell.

    I work with methyl mercaptan sometimes and it does indeed smell like concentrated rotten cabbage...a totally unforgettable smell.
