Dicyclohexylcarbodiimide hazard classification
Harmonised classification under CLP Annex VI. This is the legally binding classification in the EU; other jurisdictions may differ.
Dicyclohexylcarbodiimide pictograms and signal word
Dicyclohexylcarbodiimide 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 3 | H311 | GHS06 |
| Serious eye damage/eye irritation GHS chapter 3.3 | Category 1 | H318 | 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.
Dicyclohexylcarbodiimide hazard statements (H-codes)

| H302 | Harmful if swallowed. |
| H318 | Causes serious eye damage. |
| H317 | May cause an allergic skin reaction. |

Safety Data Sheet
Getting an SDS for Dicyclohexylcarbodiimide
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 Dicyclohexylcarbodiimi… 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
Dicyclohexylcarbodiimide precautionary statements
CLP Annex VI assigns 14 precautionary statements to Dicyclohexylcarbodiimide. 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
Dicyclohexylcarbodiimide 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 · Questions
Dicyclohexylcarbodiimide — frequently asked questions
What is the CAS number of Dicyclohexylcarbodiimide?
The CAS number of Dicyclohexylcarbodiimide is 538-75-0. Its EC number is 208-704-1.
What does a Dicyclohexylcarbodiimide label have to show?
Under CLP Annex VI the label for Dicyclohexylcarbodiimide carries the pictograms Skull and crossbones and Corrosion and the signal word is Danger.
Is Dicyclohexylcarbodiimide flammable?
CLP Annex VI assigns Dicyclohexylcarbodiimide 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 112.78 °C (235 °F), above this value (CAMEO).
Is Dicyclohexylcarbodiimide a carcinogen?
CLP Annex VI records no harmonised carcinogenicity classification for Dicyclohexylcarbodiimide. 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 Dicyclohexylcarbodiimide?
The boiling point reported for Dicyclohexylcarbodiimide is 155 °C (311 °F), range, midpoint shown, at 11 mmHg (reduced pressure) (HSDB).
What is the melting point of Dicyclohexylcarbodiimide?
The melting point reported for Dicyclohexylcarbodiimide is 34.5 °C (94.1 °F) (HSDB).
