Hey guys,

I'm trying to identify a compound and based on my IR, I have an alcohol (absorption at 3250-3500nm). It's not a carbonyl compound, because I don't have an absorption band at 1710nm. The color of the liquid is yellow, but there is an alcohol group on it. The only alcohols that I know of have clear colors to them. Anyone have any ideas as to what my unknown may be?

Thanks

mercaptan maybe?  aka methanethiol?  or thiol?

Some nitro species are yellow in color.  I know for a fact that 3-(4-nitrophenyl)propan-1-ol is yellow in color cause I was doing a synthesis with it.  In fact, any variation in the functional -OH was yellow in color (the bromide, iodide, the aldehyde, etc...)
