3,6-diazaoctanethylenediamin hazard classification
Harmonised classification under CLP Annex VI. This is the legally binding classification in the EU; other jurisdictions may differ.
3,6-diazaoctanethylenediamin pictograms and signal word
3,6-diazaoctanethylenediamin hazard class and category
| Hazard class | Category | From code | Pictogram |
|---|---|---|---|
| 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 |
| Hazardous to the aquatic environment - chronic GHS chapter 4.1 | Category 3 | H412 | — |
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.
3,6-diazaoctanethylenediamin hazard statements (H-codes)

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

Safety Data Sheet
Getting an SDS for 3,6-diazaoctanethylenediam…
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 3,6-diazaoctanethylene… 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
3,6-diazaoctanethylenediamin precautionary statements
CLP Annex VI assigns 14 precautionary statements to 3,6-diazaoctanethylenediam…. 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.
Disposal
What has to happen to the contents and the empty container.

05 · Names in the regulation
3,6-diazaoctanethylenediamin 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.

The CAS number of 3,6-diazaoctanethylenediamin is 112-24-3. Its EC number is 203-950-6.
What does a 3,6-diazaoctanethylenediamin label have to show?
Under CLP Annex VI the label for 3,6-diazaoctanethylenediamin carries the pictograms Corrosion and Exclamation mark and the signal word is Danger.
Is 3,6-diazaoctanethylenediamin flammable?
CLP Annex VI assigns 3,6-diazaoctanethylenediamin 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 143.33 °C (290 °F) (HSDB).
Is 3,6-diazaoctanethylenediamin a carcinogen?
CLP Annex VI records no harmonised carcinogenicity classification for 3,6-diazaoctanethylenediamin. 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.
