HiMedia GRM3959-500G Sodium Nitrite, Aces, 500 g

Nicely packaged with internal seal underneath the cap. Did not assay, but it produced a deep blue nitrous acid. Did not have problems with caking or moisture as others have noted.

I liked nothing about this product. Especially no MSDS sheet was post until recently which if this a lab supply agent. It should of been posted with product in Details.

Good quality, great price, and seller is quick to ship.

I was very disappointed in the quality of this. It's supposed to be ACS grade, and I wouldn't say it isn't, but I generally expect better quality from even commercial grade chemicals than this. It had a yellow tinge to it and what's much worse is that it was wet which means you can't even get accurate measurements without first processing it. What use is that?I don't know if it was packaged this way or if the package is simply poor quality and it took on moisture and oxidized, but I was not very happy to see this. If it were packaged like this, and the bottle seems rather secure and air tight so I'm inclined to think it was, then that means you're not even getting the advertised 500g. Imagine if you purchased some sugar and the bag was full of moist wet chunks instead of dry granules, you would take that back. It's far from useless, but I'm not buying this brand again if I were to purchase more NaNO2 in the future, for around the same price I can get some food grade that is white and dry.

Really good price and good quality for simple experiments...A++++

Don’t buy it. Absolutely do not buy it. Do not ever buy this. ;;;;;;;;;;
