Safety Data Sheet

Getting an SDS for 3-(2H-tetrazol-5-yl)pyridi…

A Safety Data Sheet is written for a product, not for a substance: the supplier of the grade you actually buy issues it, so two suppliers of 3-(2H-tetrazol-5-yl)py… issue two different sheets. That is why there is no single authoritative SDS for a substance to download — what there is, is the job of collecting the sheets for the products you hold and keeping them current as suppliers revise them.

04 · Precautionary statements

3-(2H-tetrazol-5-yl)pyridine precautionary statements

CLP Annex VI assigns 4 precautionary statements to 3-(2H-tetrazol-5-yl)pyridi…. They are grouped the way a label groups them: what to do before handling, what to do when something has already happened, how to store it and how to dispose of it.

Prevention

What to do before and during handling so the hazard never happens.

05 · Names in the regulation

3-(2H-tetrazol-5-yl)pyridine name in 23 EU languages

CLP Annex VI Part 3 is published in every language edition of the regulation, and the identification column is written out in each of them. Nothing below is translated by us: each line is the name as that edition prints it. Under Art. 18(2) the substance name from Annex VI is a lawful product identifier, so this is the wording to put on a label going to that market — and where the cell lists several designations, any one of them qualifies.
