What is Methyl mercaptan used for?

Methanethiol (also accepted as Methyl mercaptanis a achromatic gas with a that appears to that appears to smell like rotten cabbage. It is a accustomed actuality begin in the claret and academician of bodies and added animals as able-bodied as bulb tissues. It is disposed of through beastly feces. It occurs by itself in assertive foods, such as some basics and cheese. It is aswell one of the capital chemicals amenable for bad animation and the that appears to that appears to smell of flatus. The actinic blueprint for methanethiol is CH3SH; it is classified as a thiol. It is sometimes abbreviated as MeSH.
Methyl mercaptan is released from decaying organic matter in marshes and is present in the natural gas of certain regions, in coal tar, and in some crude oils.
In surface seawater, methanethiol is the primary breakdown product of the algal metabolite dimethylsulfoniopropionate (DMSP). Marine bacteria appear to obtain most of their protein sulfur by the breakdown of DMSP and incorporation of methanethiol, despite the fact that methanethiol is present in seawater at much lower concentrations than sulfate (~0.3 nM vs. 28 mM). Bacteria in oxic and anoxic environments can also convert methanethiol to dimethyl sulfide (DMS), although most DMS in surface seawater is produced by a separate pathway. Both DMS and methanethiol can be used by certain microbes as substrates for methanogenesis in some anaerobic soils.
Uses
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.
