lawful use pure reagents & how to not look stupid

[heavenadisaster]

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)

arg..alright fine, i'll order strikes book...

what is the title of this book you speak of?

Have you ever tried to prepare DCM with 1% water? I couldn't.

if you go into an industrial chemical supply place (where they sell in 20l drums) you won't find 99% anhydrous DCM, you will find DCM(period). the same with H2SO4, they will likely have one kind, concentrated. It is unlikely you will require an explanation for either of these other than for your own peace of mind.

you will need an explanation tho when you put some formic acid in your order

My first guess would be strikes "sources"
