03 · GHS classification

N-Octylpyrrolidone hazard classification

Harmonised classification under CLP Annex VI. This is the legally binding classification in the EU; other jurisdictions may differ.

N-Octylpyrrolidone hazard class and category

GHS hazard classes N-Octylpyrrolidone falls into
Hazard class Category From code Pictogram
Skin corrosion/irritation GHS chapter 3.2 Category 1A or 1B or 1C H314 GHS05
Hazardous to the aquatic environment - chronic GHS chapter 4.1 Category 2 H411 GHS09

Where two values are shown with “or”, the hazard statement is shared by more than one category or by more than one class, and the code alone does not say which. H272, for example, belongs to oxidising liquids and to oxidising solids — the physical state decides. The binding answer for a specific entry is in the CLP Annex VI table itself.

Safety Data Sheet

Getting an SDS for N-Octylpyrrolidone

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 N-Octylpyrrolidone 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

N-Octylpyrrolidone precautionary statements

CLP Annex VI assigns 8 precautionary statements to N-Octylpyrrolidone. 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.

05 · Names in the regulation

N-Octylpyrrolidone 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.

08 · Questions

N-Octylpyrrolidone — frequently asked questions

What is the CAS number of N-Octylpyrrolidone?

The CAS number of N-Octylpyrrolidone is 2687-94-7. Its EC number is 403-700-8.

What is the chemical formula of N-Octylpyrrolidone?

The molecular formula of N-Octylpyrrolidone is C12H23NO and its molecular weight is 197.32 g/mol.

What does a N-Octylpyrrolidone label have to show?

Under CLP Annex VI the label for N-Octylpyrrolidone carries the pictograms Corrosion and Environment and the signal word is Danger.

Is N-Octylpyrrolidone flammable?

CLP Annex VI assigns N-Octylpyrrolidone 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 N-Octylpyrrolidone a carcinogen?

CLP Annex VI records no harmonised carcinogenicity classification for N-Octylpyrrolidone. 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.
