Methanethiol 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. It occurs in various plants and vegetables, such as radishes. In surface seawater, methanethiol is the primary breakdown product of the algal metabolite dimethylsulfoniopropionate (DMSP).
(Methylthio)methanethiol (MeSCH 2 SH; MTMT) is a strong-smelling volatile thiol, also detectable at parts per billion levels, found in male mouse urine. Lawrence C. Katz and co-workers showed that MTMT functioned as a semiochemical , activating certain mouse olfactory sensory neurons, and attracting female mice . [ 17 ]
Lewis structure of a water molecule. Lewis structures – also called Lewis dot formulas, Lewis dot structures, electron dot structures, or Lewis electron dot structures (LEDs) – are diagrams that show the bonding between atoms of a molecule, as well as the lone pairs of electrons that may exist in the molecule.
Different ways of representing a methyl group (highlighted in blue). In organic chemistry, a methyl group is an alkyl derived from methane, containing one carbon atom bonded to three hydrogen atoms, having chemical formula CH 3 (whereas normal methane has the formula CH 4).
Ethanethiol, commonly known as ethyl mercaptan, is an organosulfur compound with the formula CH 3 CH 2 SH. [5] It is a colorless liquid with a distinct odor. Abbreviated EtSH, it consists of an ethyl group (Et), CH 3 CH 2, attached to a thiol group, SH.

Sodium methanethiolate or sodium thiomethoxide (CH 3 SNa, MeSNa) is the sodium conjugate base of methanethiol.This compound is commercially available as a white solid. It is a powerful nucleophile that can be used to prepare methylthioether and other organic compounds like ethyl bromide.
Methional is synthesized commercially by the reaction of methanethiol and acrolein. [3] CH 3 SH + CH 2 =CHCHO → CH 3 SCH 2 CH 2 CHO. Using the Strecker synthesis, methional is converted to methionine. For the purpose of animal feed supplements, enantiopure methionine is not required. [3] Methional is a versatile reagent in organic chemistry. [4]
