Safety Data Sheet
Getting an SDS for Perfluoroheptanoic acid
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 Perfluoroheptanoic… 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
Perfluoroheptanoic acid precautionary statements
CLP Annex VI assigns 3 precautionary statements to Perfluoroheptanoic acid. 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
Perfluoroheptanoic acid 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.

09 · Questions
Perfluoroheptanoic acid — frequently asked questions
What is the CAS number of Perfluoroheptanoic acid?
The CAS number of Perfluoroheptanoic acid is 375-85-9. Its EC number is 206-798-9.
What is the chemical formula of Perfluoroheptanoic acid?
The molecular formula of Perfluoroheptanoic acid is C7HF13O2 and its molecular weight is 364.06 g/mol.
What does a Perfluoroheptanoic acid label have to show?
Under CLP Annex VI the label for Perfluoroheptanoic acid carries the pictogram Health hazard and the signal word is Danger.
Is Perfluoroheptanoic acid flammable?
CLP Annex VI assigns Perfluoroheptanoic acid 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 113 °C (235.4 °F), above this value (HSDB).
Is Perfluoroheptanoic acid a carcinogen?
CLP Annex VI records no harmonised carcinogenicity classification for Perfluoroheptanoic acid. 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 boiling point of Perfluoroheptanoic acid?
The boiling point reported for Perfluoroheptanoic acid is 175 °C (347 °F) (HSDB).
What is the melting point of Perfluoroheptanoic acid?
