Safety Data Sheet

Getting an SDS for N,N-Diethylaniline

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,N-Diethylaniline 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,N-Diethylaniline precautionary statements

CLP Annex VI assigns 14 precautionary statements to N,N-Diethylaniline. 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,N-Diethylaniline 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.

What does a N,N-Diethylaniline label have to show?

Under CLP Annex VI the label for N,N-Diethylaniline carries the pictograms Skull and crossbones, Health hazard and Environment and the signal word is Danger.

Is N,N-Diethylaniline flammable?

CLP Annex VI assigns N,N-Diethylaniline 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 85 °C (185 °F) (HSDB).

Is N,N-Diethylaniline a carcinogen?

CLP Annex VI records no harmonised carcinogenicity classification for N,N-Diethylaniline. 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 N,N-Diethylaniline?

The boiling point reported for N,N-Diethylaniline is 216.3 °C (421.3 °F) (HSDB).

What is the melting point of N,N-Diethylaniline?
