Because I always have a Menda bottle full of high-purity alcohol on the electronics bench, I find many uses for it.
If I had to drive to Radio Shack every ounce or so to get a refill, I would doubtless not bother for most jobs.

I mean assemble the molecules from bulk quantities of their constituent elements. :) Chemical engineering.
As my measurement data in the post I just sent hints, there are serious practical problems -- aside from the direct economic ones -- that restrict the utility of such high-purity alcohols. There's probably no point using it outside a cleanroom. Dust on the glassware will wreck the purity rating otherwise.
