Need some help please...do either of these sound like good SN?

[GoingHome11:11]

I'm not sure if I can ask this on here, if not, hopefully it will just be deleted.

Can anyone look at these specifications and tell me whether or not they would be good SN? They don't list a purity %, only an assay % and I'm not sure what that means? Any help would be really, greatly appreciated. I'm so lost when it comes to figuring this all out with SN.

What is the cas number ( cas no )?

Here it says NitrAte but not NitrIte.

Linear Formula - NaNO2
Formula Weight - 69

That is Nitrite.

That's a bit confusing.

If I remember assay is purity, but I could be wrong, maybe other member could help you
Sorry if I make mistake

What is the cas number ( cas no )?

I'm not sure what the cas number means, but they both have the same, it's 7632-00-0. Can you tell me more about it?

 

[Praestat_Mori]

The CAS number seems to be correct.

That is Nitrite.

Oh, you're right! Thank you, I didn't even catch that. I may have to reach out to someone to verify.

Chemical Abstracts Service (CAS) Number: A unique accession number assigned by the Chemical Abstracts Service, a division of the American Chemical Society.

SN CAS NO: 7632-00-0, correct.

Really good to know. Thanks so much for this!

Correct, assay = purity. Both 97% and 99% are high purity
