My guess re. the reagent sign is that it came from a lab. For example, for ethanol, I would see drums in central supply rooms marked "Denatured" (sometimes with the # for the formula), "Technical" and "Reagent grade." Normally you couldn't use one for the other. And the reagent was guarded like Fort Knox!
