Twisted sense of Humour

[Old Possum]

Hello all.
In Australia, we add ethane thiol to the natrual/LPG gas to give it a unique odour.
I have in my stores here 2 L of ethane thiol in 500 mL bottles, they have never been opened, they are still sealed, they still contain 500 mL each, they are stored in my 4 degC Fridge, and whenever I open that fridge, I stink out the entire floor of the building. (7500 m3) Humans are especially sensitive to ethane thiol, we can smell it at concentrations as low as 1 part per 50 BILLION. Also when I used to work in a mine, ethane thiol was used as the Emergency evacuation notifaction; As it will pass straight through any air filter or scrubber in existence, in addition to having a very rapid dispersion speed. If you ever smelt etahne thiol while down in the mine, that meant you must evacuate immediately.
BTW pretty much all noxious smelling compounds contain sulphur ( thiols ,thioethers, or sulphoxides )

Yep. Ethanethiol is ethyl mercaptan--both methanethiol/methyl mercaptan and ethanethiol/ethyl mercaptan are pretty pungent. In my lab we commonly use 2-mercaptoethanol (OH-CH[sub]2[/sub]-CH[sub]2[/sub]-SH), which is pretty bad itself, though in reality not as bad as TEMED (tetraethylmethylenediamine). Both of these we use in dealing with proteins, though we keep them in much smaller quantities than what Possum describes (<25 mL).
