Dipropylamine
Dipropylamine is a colorless liquid with an ammonia odor.
01 · Identification
What Dipropylamine is
Dipropylamine is a colorless liquid with an ammonia odor. It boils at 109 °C, melts at -63 °C.
Under the GHS it carries the signal word Danger. It is classed as flammable agents - 3rd degree.

03 · GHS classification
Dipropylamine hazard classification
Harmonised classification under CLP Annex VI. This is the legally binding classification in the EU; other jurisdictions may differ.
Dipropylamine pictograms and signal word
Dipropylamine hazard class and category
| Hazard class | Category | From code | Pictogram |
|---|---|---|---|
| Flammable liquids GHS chapter 2.6 | Category 2 | H225 | GHS02 |
| Acute toxicity - oral GHS chapter 3.1 | Category 4 | H302 | GHS07 |
| Acute toxicity - dermal GHS chapter 3.1 | Category 4 | H312 | GHS07 |
| Acute toxicity - inhalation GHS chapter 3.1 | Category 4 | H332 | GHS07 |
| Skin corrosion/irritation GHS chapter 3.2 | Category 1A or 1B or 1C | H314 | GHS05 |
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.
Dipropylamine hazard statements (H-codes)
| Code | Hazard statement |
|---|---|
| H225 | Highly flammable liquid and vapour. |
| H332 | Harmful if inhaled. |
| H312 | Harmful in contact with skin. |
| H302 | Harmful if swallowed. |
| H314 | Causes severe skin burns and eye damage. |

Safety Data Sheet
Getting an SDS for Dipropylamine
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 Dipropylamine 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
Dipropylamine precautionary statements
CLP Annex VI assigns 17 precautionary statements to Dipropylamine. 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
Dipropylamine 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.

10 · Handling and storage
Dipropylamine storage and handling
Dipropylamine storage conditions
Before entering a confined space where this chemical may be present, check to make sure that an explosive concentration does not exist. Store in Tightly closed containers in a cool, well-ventilated area. Metal containers involving the transfer of this chemical should be grounded and bonded. Where possible, automatically pump liquid from drums or other storage containers to process containers. Drums must be equipped with self-closing valves, pressure vacuum bungs, and flame arresters. Use only non-sparking tools and equipment, especially when opening and closing containers of this chemical. Sources of ignition such as smoking and open flames are prohibited where this chemical is used, handled, or stored in a manner that could create a potential fire or explosion hazard. Wherever this chemical is used, handled, manufactured, or stored, use explosion-proof electrical equipment and fittings.

Transport classification is a separate system from the GHS classification above. It decides how a package is marked and how a load may be carried; it does not follow from the workplace label, and the workplace label does not follow from it. The entries below are linked by CAS number, never by name.

Dipropylamine — frequently asked questions
What is the CAS number of Dipropylamine?
The CAS number of Dipropylamine is 142-84-7. Its EC number is 205-565-9.
What does a Dipropylamine label have to show?
Under CLP Annex VI the label for Dipropylamine carries the pictograms Flame, Corrosion and Exclamation mark and the signal word is Danger.
Is Dipropylamine flammable?
Yes. CLP Annex VI assigns Dipropylamine H225 — highly flammable liquid and vapour. The flash point reported for it is 17.22 °C (63 °F) (HSDB).
Is Dipropylamine a carcinogen?
CLP Annex VI records no harmonised carcinogenicity classification for Dipropylamine. 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 Dipropylamine?
The boiling point reported for Dipropylamine is 109.3 °C (228.7 °F) (HSDB).
What is the melting point of Dipropylamine?
The melting point reported for Dipropylamine is -63 °C (-81.4 °F) (HSDB).
How should Dipropylamine be stored?
CLP Annex VI assigns Dipropylamine the storage statement P403. Before entering a confined space where this chemical may be present, check to make sure that an explosive concentration does not exist. Store in Tightly closed containers in a cool, well-ventilated area. Metal containers involving the transfer of this chemical should be grounded and bonded. Where possible, automatically pump liquid from drums or other storage containers to process containers. Drums must be equipped with self-closing valves, pressure vacuum bungs, and flame arresters. Use only non-sparking tools and equipment, especially when opening and closing containers of this chemical. Sources of ignition such as smoking and open flames are prohibited where this chemical is used, handled, or stored in a manner that could create a potential fire or explosion hazard. Wherever this chemical is used, handled, manufactured, or stored, use explosion-proof electrical equipment and fittings. (Hazardous Substances Data Bank (HSDB))
