Help SN Acs or AR

[ImmortalTaoist]

Hello, I'm looking into SN and there's 2 forms popping up, SN and AR and idk what the difference is to be fair and I want to know what it is or which one is the proper one to get as I can't find info on what's what

I don't know what AR could be, but until further notice: If it's SN I want, I'll stick with SN.

Ah, the blind leading the blind. AR and ACS are variants of a brand of SN.

AR is an acronym for analytical reagent. It just means the SN has high purity. See https://chemistry.stackexchange.com/questions/140274/what-does-a-r-in-a-r-sodium-nitrite-mean
