2,2'-[[3-methyl-4-[(4-nitrophe… hazard class and category

GHS hazard classes 2,2'-[[3-methyl-4-[(4-nitr… falls into
Hazard class Category From code Pictogram
Skin sensitisation GHS chapter 3.4 Category 1 or 1A or 1B H317 GHS07

Where two values are shown with “or”, the hazard statement is shared by more than one category or by more than one class, and the code alone does not say which. H272, for example, belongs to oxidising liquids and to oxidising solids — the physical state decides. The binding answer for a specific entry is in the CLP Annex VI table itself.

Safety Data Sheet

Getting an SDS for 2,2'-[[3-methyl-4-[(4-nitr…

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 2,2'-[[3-methyl-4-[(4… 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

2,2'-[[3-methyl-4-[(4-nitrophe… precautionary statements

CLP Annex VI assigns 5 precautionary statements to 2,2'-[[3-methyl-4-[(4-nitr…. 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.

Response

05 · Names in the regulation

2,2'-[[3-methyl-4-[(4-nitrophe… name in 22 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.

22 of the 23 language editions carry this entry; it is absent from Portuguese. That is a property of the regulation, not a gap in this table — editions do occasionally differ in which entries they print. Irish is the twenty-fourth official EU language and has no line here for a different reason: no consolidated CLP text has ever been published in Irish, so there is no Irish edition of Annex VI to quote a name from.
