when buy reagent grade reagents from local chem supply, many bees speak of claiming industrial use. ..why would an industrial plexiglass worker need 99.9% anhydrous DCM to use on his plexiglass? why would a plumber need conc h2so4 for clogged drains when he could just go get it diluted as drain cleaner in the hardware store?
would other bees recommend strategies? would it be better to find lawful uses of the chemicals that still require a certain standard of purity? what would be some examples of these? (ie. chemical -> legit reagent grade use)
