Safety Data Sheet
Getting an SDS for 2-(Octylthio)ethanol
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-(Octylthio)ethanol 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-(Octylthio)ethanol precautionary statements
CLP Annex VI assigns 4 precautionary statements to 2-(Octylthio)ethanol. 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.

05 · Names in the regulation
2-(Octylthio)ethanol 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.

2-(Octylthio)ethanol UN number and transport classification
Transport classification is a separate system from the GHS classification above. It decides how a package is marked and how a load may be carried; it does not follow from the workplace label, and the workplace label does not follow from it. The entries below are linked by CAS number, never by name.

What is the CAS number of 2-(Octylthio)ethanol?
The CAS number of 2-(Octylthio)ethanol is 3547-33-9. Its EC number is 222-598-4.
What is the chemical formula of 2-(Octylthio)ethanol?
The molecular formula of 2-(Octylthio)ethanol is C10H22OS and its molecular weight is 190.35 g/mol.
What does a 2-(Octylthio)ethanol label have to show?
Under CLP Annex VI the label for 2-(Octylthio)ethanol carries the pictogram Corrosion and the signal word is Danger.
Is 2-(Octylthio)ethanol flammable?

Is 2-(Octylthio)ethanol a carcinogen?
CLP Annex VI records no harmonised carcinogenicity classification for 2-(Octylthio)ethanol. 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.
