A chem company is selling some stuff I need in technical grade but I can get most from my local hardware store. I think the hardware chems are just
technical grade anyway eh? What would be purer?

Tech grade from chem company are certified and purer, while from hardware store they aren't certified and might contain others, voluntary or not,
impurity. If you have the chance to use tech grade from a chem supplier, trust me you better go with it, depending on what you want, I personnaly
prefer to pay a bit more and have less purification and more product at the end, than use cheap regeant and have low yield with lot of shit in it.

In some cases, it all comes out of the same tank car.
I used to use hardware store acetone for doing total chrome tests (it's the solvent for the color reagent) and it worked just fine.

In my somewhat limited real of knowledge, I believe that it depends a good deal on purpose and what you intend to use the chemicals for.
Sometimes hardware store chemicals are fine and others not. Perhaps, you could tell us what the chemical is and what purpose and from that we can hope
to ascertain if they are suitable.
If not then good luck.

Thanks for the excellent responses to my question. The chems that I nedd are manily solvents and they will be used in many procedures so its hard to
state a single one.
These are some:
acetone
dcm/chloroform
naphtha
denatured alcohol
ether
methanol
If someone can recommend some hardware store (or from whatever store) brands etc that would be assume.

Ace Hardware has the acetone, toluene, naptha.
Co-op or other ag supply places have the methanol which is used to keep the water in tractor tires from freezing in the winter.
DCM can be had at online fiberglass and pyro suppliers, and in aircraft stripper at most stores (unlike the former will have to be distilled before
use).
Denatured alcohol can also be had at Ace, but its roughly a 50-50 blend of ethyl and methyl alcohol.
Chloroform or ether, might as well hang those two up unless you make your own. Ether and chloroform are controlled and heavily watched. It is possible
to make your own in both cases, but its a pain in the ass.

Ether blended with ethanol or heptane is available in spray cans as "cold start"
carburation fluid from automotive products suppliers. One such is _
