Safety Data Sheet
Getting an SDS for 1,3-Dichlorobenzene
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 1,3-Dichlorobenzene 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
1,3-Dichlorobenzene precautionary statements
CLP Annex VI assigns 7 precautionary statements to 1,3-Dichlorobenzene. 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.
Response
What to do once exposure, spillage or fire has already happened.
Disposal
What has to happen to the contents and the empty container.

05 · Names in the regulation
1,3-Dichlorobenzene 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.

An IARC group and a CLP classification answer different questions. IARC judges whether the evidence for cancer in humans is strong enough; CLP Annex VI is the legally binding EU classification. A substance can carry one and not the other.

11 · Questions
1,3-Dichlorobenzene — frequently asked questions
What is the CAS number of 1,3-Dichlorobenzene?
The CAS number of 1,3-Dichlorobenzene is 541-73-1. Its EC number is 208-792-1.
What is the chemical formula of 1,3-Dichlorobenzene?

What does a 1,3-Dichlorobenzene label have to show?
Under CLP Annex VI the label for 1,3-Dichlorobenzene carries the pictograms Exclamation mark and Environment and the signal word is Warning.
Is 1,3-Dichlorobenzene flammable?
CLP Annex VI assigns 1,3-Dichlorobenzene 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. The flash point reported for it is 63.33 °C (146 °F) (CAMEO).
Is 1,3-Dichlorobenzene a carcinogen?
CLP Annex VI records no harmonised carcinogenicity classification for 1,3-Dichlorobenzene. 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. IARC places it in Group 3: not classifiable as to its carcinogenicity to humans.
What is the boiling point of 1,3-Dichlorobenzene?
The boiling point reported for 1,3-Dichlorobenzene is 173 °C (343.4 °F) (HSDB).
What is the melting point of 1,3-Dichlorobenzene?
