Safety Data Sheet
Getting an SDS for Cuprous thiocyanate
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 Cuprous thiocyanate 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
Cuprous thiocyanate precautionary statements
CLP Annex VI assigns 3 precautionary statements to Cuprous thiocyanate. 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.
Disposal
What has to happen to the contents and the empty container.

05 · Names in the regulation
Cuprous thiocyanate 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 is the CAS number of Cuprous thiocyanate?
The CAS number of Cuprous thiocyanate is 1111-67-7. Its EC number is 214-183-1.
What is the chemical formula of Cuprous thiocyanate?
The molecular formula of Cuprous thiocyanate is CCuNS and its molecular weight is 121.63 g/mol.
What does a Cuprous thiocyanate label have to show?
Under CLP Annex VI the label for Cuprous thiocyanate carries the pictogram Environment and the signal word is Warning.
Is Cuprous thiocyanate flammable?
CLP Annex VI assigns Cuprous thiocyanate 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 Cuprous thiocyanate a carcinogen?
CLP Annex VI records no harmonised carcinogenicity classification for Cuprous thiocyanate. 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 exposure limit for Cuprous thiocyanate?
The US occupational exposure limit reported for Cuprous thiocyanate is 1.0 [mg/m3], as Cu (Haz-Map, Information on Hazardous Chemicals and Occupational Diseases). Limits differ by country: the EU sets its own indicative and binding values, and the figure that applies at a given workplace is the one in the local regulation.
