Thiophenols smell like hell, concentrated stuff will make you want to vomit, totally not like gasoline.

It is however true that TLC can sometimes show a pale spot of a side product while this is invisible on NMR. I think this is only the case when the
side product has an unusually high UV absorption or fluorescence, since this does not happen often to me and when it does the spot most commonly
shines at the 366nm light. |
I've had them show up on 254nm too. But then again I'm often making monomers for polycondensations, which requires you don't have any chain terminator
at all present.

I'll determine the boiling point anywhere soon so then I can say more about if it actually is the thiol.
Also an GC-MS and NMR will be taken next week, I'll keep you updated.
