Ethanethiol was originally reported by Zeise in 1834. [7] Zeise treated calcium ethyl sulfate with a suspension of barium sulfide saturated with hydrogen sulfide. He is credited with naming the C 2 H 5 S- group as mercaptum. Ethanethiol can also be prepared by a halide displacement reaction, where ethyl halide is treated with aqueous sodium ...

Diethyl sulfide is a by-product of the commercial production of ethanethiol, which is prepared by the reaction of ethylene with hydrogen sulfide over an alumina-based catalyst. The amount of diethyl sulfide produced can be controlled by varying the ratio of hydrogen sulfide to ethylene.
Thiol with a blue highlighted sulfhydryl group.. In organic chemistry, a thiol (/ ˈ θ aɪ ɒ l /; [1] from Ancient Greek θεῖον (theion) 'sulfur' [2]), or thiol derivative, is any organosulfur compound of the form R−SH, where R represents an alkyl or other organic substituent.
Toxicity may be due to metabolism products hydrogen sulfide and acetaldehyde, however as used it has a margin of safety of over 10,000,000. [2] Other ways that it is modified in the body apart from hydrolysis is methylation to 1-methylsulfanyl-ethanethiol, oxidation of the sulfur to an ethyl sulfonate, glucuronidation of the sulfur, or ...
ACS settings should be used for both structures and reaction schemes. These settings are normally available as templates in chemical drawing programs. Use sans-serif fonts like Arial. Indexes used for labelling must be superscripted: R 1-CH 2-R 2 (not R 1-CH 2-R 2) Do not include English text in images: this prevents their reuse in other languages.
Methanethiol is mainly used to produce the essential amino acid methionine, which is used as a dietary component in poultry and animal feed. [10] Methanethiol is also used in the plastic industry as a moderator for free-radical polymerizations [ 10 ] and as a precursor in the manufacture of pesticides .
1,2-Ethanedithiol has been used as a scavenger in peptide cleavage synthesis. [citation needed] Like 1,3-propanedithiol, 1,2-ethanedithiol readily forms metal thiolate complexes. Illustrative is the synthesis of the derivative diiron ethanedithiolate hexacarbonyl upon reaction with triiron dodecacarbonyl: [5]
