is this the same as the mercaptan that is added to gas for the smell? -- Tarquin 19:39 7 Jun 2003 (UTC)
I was asked for comment on a motion to move this article to methanethiol. I would oppose this move. Although methanethiol is the IUPAC name of the chemical, methyl mercaptan is, in my experience, the more commonly-used name (although I wouldn't claim that either one is universally used). The situation is somewhat similar to chloroform; while trichloromethane its IUPAC name, it is much more broadly called chloroform.
Note also that several articles link here, while few link to methanethiol. Aerion //talk 19:33, 6 Apr 2005 (UTC)
"Mercaptan" is in somewhat common usage (unlike thiol), but I not so sure "methyl mercaptan" is. Mercaptan already redirects to thiol. (I abstain on the move) - R. S. Shaw 02:58, 7 Apr 2005 (UTC)
A simple Google test shows 13,900 results for Methanethiol and 40,000 for Methyl mercaptan. Based on that and no other knowledge of the subject I'm going to oppose the move. violet/riga (t) 09:16, 7 Apr 2005 (UTC)
This article has been renamed as the result of a

Is there a biological or evolutionary reason why it smells so disgusting to humans? Do we have a special hard-wired centre to react to it? Are there animals who also find it disgusting, or some who find it smells nice? etc. I would love to see the article expanded in this direction.-- Sonjaaa 19:15, 8 January 2007 (UTC)

Hello,
I understand that Methanethiol can be neutralised with weak hypochlorite solutions, but does anyone know a source for this? 129.78.208.4 03:45, 10 January 2007 (UTC)
I removed the block below for being unencyclopedic. However, it is good information that could be added back in if it was reworked. -- Mdwyer 05:19, 1 February 2007 (UTC)
As a result of a tragic explosion March 18, 1937 in New London, Texas when the high school exploded and 311 people were killed, (see link: www.nlse.org/tm0307.html ) the Texas Legislature established law requiring smell (Mercaptan) to be added to natural gas which is odorless to allow the smell to be detectable and the danger of a gas leak to be humanly detectable. The law also extablished the Texas Board for Professional Engineers to regulate and encourage professionalism and safety in engineering applications. Interestingly energy companies like Gulf Oil immediately began adding Mercaptan to their natural gas distributions and even started adding Mercaptan to natural gas at source even in Venezuela where there were no laws requiring this but where the obvious safety aspects were also applied.

I would suggest that one then visit the sites of odorant manufacturers Chevron Phillips Chemical Co or Arkema Chemicals to note that methanethiol is not sold as a gas odorant. The Bureau of Mines did not study methanethiol in its' investigations of gas odorants in the late 1920's. As well as the gas odorant literature (see Institute of Gas Technology/Gas Technology Institute as well as the American Gas Association.
The 1937 incident in New London prompted Texas to encode a requirement for odorization of gas. This was followed shortly by the US DOT. Many gas companies had been using odorants prior to this, but not because they were required to. Much coal gas was quite odorous. Natural gas usage was not wide spread in this time frame, as much of the pipeline infrastructure had yet to be built.
Also, please note that several of the "incidents" in this section are attributed to natural gas odorants, which are definitely not methanethiol. John Roberts —Preceding undated comment added 12:08, 20 May 2012 (UTC).
I've done a little looking at these and the sources closer to the incident report a substance called Merkantan. Some sources are indicating LPG odorant. This is ethanethiol, not methanethiol. The Milan and SF Bay incidents are both natural gas odorants and not methanethiol. I am suggesting that the Incidents section be removed from this topic. JSR ( talk) 19:09, 20 May 2012 (UTC) I
