Safety Data Sheet
Getting an SDS for Cyanazine
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 Cyanazine 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
Cyanazine precautionary statements
CLP Annex VI assigns 7 precautionary statements to Cyanazine. 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
Cyanazine 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.

Cyanazine carcinogenicity classification
Cancer Classification: Group C Possible Human Carcinogen

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.

10 · Questions
Cyanazine — frequently asked questions
What is the CAS number of Cyanazine?
The CAS number of Cyanazine is 21725-46-2. Its EC number is 244-544-9.
What is the chemical formula of Cyanazine?
The molecular formula of Cyanazine is C9H13ClN6 and its molecular weight is 240.69 g/mol.
What does a Cyanazine label have to show?
Under CLP Annex VI the label for Cyanazine carries the pictograms Exclamation mark and Environment and the signal word is Warning.
Is Cyanazine flammable?
CLP Annex VI assigns Cyanazine 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 Cyanazine a carcinogen?
CLP Annex VI records no harmonised carcinogenicity classification for Cyanazine. 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 Cyanazine?
The melting point reported for Cyanazine is 168 °C (334.4 °F) (ICSC).
How should Cyanazine be stored?
Keep from domestic animals, particularly cattle. (Hazardous Substances Data Bank (HSDB))
