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.
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).
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]
Furan-2-ylmethanethiol (2-furanmethanethiol) is an organic compound containing a furan substituted with a sulfanylmethyl group. It is a clear colourless liquid when pure, but it becomes yellow coloured upon prolonged standing.

In industry, methanethiol is prepared by the reaction of hydrogen sulfide with methanol. This method is employed for the industrial synthesis of methanethiol: CH 3 OH + H 2 S → CH 3 SH + H 2 O. Such reactions are conducted in the presence of acidic catalysts. The other principal route to thiols involves the addition of hydrogen sulfide to ...
