2-chloro-1,3,5-trinitrobenzene hazard class and category

GHS hazard classes 2-chloro-1,3,5-trinitroben… falls into
Hazard class Category From code Pictogram
Explosives GHS chapter 2.1 Category 1.1 H201 GHS01
Acute toxicity - oral GHS chapter 3.1 Category 1 or 2 H300 GHS06
Acute toxicity - dermal GHS chapter 3.1 Category 1 or 2 H310 GHS06

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-chloro-1,3,5-trinitroben…

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-chloro-1,3,5-trinitr… 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-chloro-1,3,5-trinitrobenzene precautionary statements

CLP Annex VI assigns 14 precautionary statements to 2-chloro-1,3,5-trinitroben…. 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.

05 · Names in the regulation

2-chloro-1,3,5-trinitrobenzene 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.

All 23 language editions of Annex VI carry this entry. 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.

What does a 2-chloro-1,3,5-trinitrobenzene label have to show?

Under CLP Annex VI the label for 2-chloro-1,3,5-trinitrobenzene carries the pictograms Exploding bomb, Skull and crossbones and Environment and the signal word is Danger.

Is 2-chloro-1,3,5-trinitrobenzene flammable?

CLP Annex VI assigns 2-chloro-1,3,5-trinitrobenzene no flammability hazard class. That is not a statement that it cannot burn: the harmonised list only records the hazards that were assessed for it.

Is 2-chloro-1,3,5-trinitrobenzene a carcinogen?

CLP Annex VI records no harmonised carcinogenicity classification for 2-chloro-1,3,5-trinitrobenzene. Annex VI is a list of agreed classifications, not a list of substances found safe, so this is an absence of a classification rather than a clean bill of health.

What is the melting point of 2-chloro-1,3,5-trinitrobenzene?

The melting point reported for 2-chloro-1,3,5-trinitrobenzene is 83 °C (181.4 °F) (HSDB).
