03 · GHS classification
2,2'-iminodiethylamine hazard classification
Harmonised classification under CLP Annex VI. This is the legally binding classification in the EU; other jurisdictions may differ.
2,2'-iminodiethylamine pictograms and signal word
2,2'-iminodiethylamine hazard class and category
| Hazard class | Category | From code | Pictogram |
|---|---|---|---|
| Acute toxicity - oral GHS chapter 3.1 | Category 4 | H302 | GHS07 |
| Acute toxicity - dermal GHS chapter 3.1 | Category 4 | H312 | GHS07 |
| Skin corrosion/irritation GHS chapter 3.2 | Category 1A or 1B or 1C | H314 | GHS05 |
| Skin sensitisation GHS chapter 3.4 | Category 1 or 1A or 1B | H317 | GHS07 |
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.
2,2'-iminodiethylamine hazard statements (H-codes)

| H302 | Harmful if swallowed. |
| H314 | Causes severe skin burns and eye damage. |
| H317 | May cause an allergic skin reaction. |

Safety Data Sheet
Getting an SDS for 2,2'-iminodiethylamine
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 2,2'-iminodiethylamine 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
2,2'-iminodiethylamine precautionary statements
CLP Annex VI assigns 14 precautionary statements to 2,2'-iminodiethylamine. 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
2,2'-iminodiethylamine 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.

2,2'-iminodiethylamine incompatible materials
Explosive solutions of nitromethane in dichloromethane, sensitized by addition of 10-12% of /bis(2-aminoethyl)amine/, retained their sensitivity at -50 °C. Presence of 0-5% of the triamine considerable increases detonation sensitivity of nitromethane.

2,2'-iminodiethylamine reactivity
DIETHYLENETRIAMINE 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.

2,2'-iminodiethylamine — frequently asked questions
What is the CAS number of 2,2'-iminodiethylamine?
The CAS number of 2,2'-iminodiethylamine is 111-40-0. Its EC number is 203-865-4.
What does a 2,2'-iminodiethylamine label have to show?
Under CLP Annex VI the label for 2,2'-iminodiethylamine carries the pictograms Corrosion and Exclamation mark and the signal word is Danger.
Is 2,2'-iminodiethylamine flammable?
CLP Annex VI assigns 2,2'-iminodiethylamine 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 101.7 °C (215.1 °F), Open cup (HSDB).
Is 2,2'-iminodiethylamine a carcinogen?
CLP Annex VI records no harmonised carcinogenicity classification for 2,2'-iminodiethylamine. 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 exposure limit for 2,2'-iminodiethylamine?
The US occupational exposure limit reported for 2,2'-iminodiethylamine is 10 ppm (42 mg/m³) (Construction and Maritime only) (Occupational Safety and Health Administration (OSHA)). Limits differ by country: the EU sets its own indicative and binding values, and the figure that applies at a given workplace is the one in the local regulation.
What is the boiling point of 2,2'-iminodiethylamine?
The boiling point reported for 2,2'-iminodiethylamine is 207 °C (404.6 °F), at 760 mmHg (HSDB).
What is the melting point of 2,2'-iminodiethylamine?
The melting point reported for 2,2'-iminodiethylamine is -39 °C (-38.2 °F) (HSDB).
