Analytical Reagent SN on SD Purity?

[greyblue_bian]

I've heard a lot about the Food Grade SN they have on their site and I've seen it been tested multiple times here, but I barely see anyone discuss the purity of the cheaper option and if anyone's tested it. Has anyone here purchased before and tested the purity? Was it pure enough to CTB with? Deciding to purchase today since I'm in rush because of the law being passed.

I purchased analytical reagent as the purity was listed as higher (99.89%) & a lil cheaper, which was confusing. would love to hear if anyone tested/it's legit prior to when my package arrives so I can either move quickly with ctb or another source, thank you!
