Safety Data Sheet

Getting an SDS for Octadecylamine

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 Octadecylamine 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

Octadecylamine precautionary statements

CLP Annex VI assigns 15 precautionary statements to Octadecylamine. 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

Octadecylamine 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.

Octadecylamine reactivity

OCTADECYLAMINE neutralizes acids in exothermic reactions to form salts plus water. May be incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides. Flammable gaseous hydrogen may be generated in combination with strong reducing agents, such as hydrides.

What is the chemical formula of Octadecylamine?

The molecular formula of Octadecylamine is C18H39N and its molecular weight is 269.5 g/mol.

What does a Octadecylamine label have to show?

Under CLP Annex VI the label for Octadecylamine carries the pictograms Corrosion, Health hazard and Environment and the signal word is Danger.

Is Octadecylamine flammable?

CLP Annex VI assigns Octadecylamine 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 148.89 °C (300 °F) (CAMEO).

Is Octadecylamine a carcinogen?

CLP Annex VI records no harmonised carcinogenicity classification for Octadecylamine. 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 Octadecylamine?

The boiling point reported for Octadecylamine is 346.8 °C (656.2 °F), at 760 mmHg (HSDB).

What is the melting point of Octadecylamine?
