Safety Data Sheet

Getting an SDS for Nonanoic 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 Nonanoic Acid 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

Nonanoic Acid precautionary statements

CLP Annex VI assigns 11 precautionary statements to Nonanoic 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.

Disposal

05 · Names in the regulation

Nonanoic 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.

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 does a Nonanoic Acid label have to show?

Under CLP Annex VI the label for Nonanoic Acid carries the pictogram Exclamation mark and the signal word is Warning.

Is Nonanoic Acid flammable?

CLP Annex VI assigns Nonanoic 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 133 °C (271.4 °F), open cup (HSDB).

Is Nonanoic Acid a carcinogen?

CLP Annex VI records no harmonised carcinogenicity classification for Nonanoic 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.

The boiling point reported for Nonanoic Acid is 254.5 °C (490.1 °F) (HSDB).

What is the melting point of Nonanoic Acid?

The melting point reported for Nonanoic Acid is 12.4 °C (54.3 °F) (HSDB).

How should Nonanoic Acid be stored?

Do not contaminate water, food, or feed by storage... . Keep conatiner tightly sealed when not in use. Store only in original container in a dry place inaccessible to children and pets. /Scythe herbicide (57% pelargonic acid)/ (Hazardous Substances Data Bank (HSDB))
