Harmonised classification under CLP Annex VI. This is the legally binding classification in the EU; other jurisdictions may differ.
Dicofol pictograms and signal word
Dicofol 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 2 | H315 | GHS07 |
| Skin sensitisation GHS chapter 3.4 | Category 1 or 1A or 1B | H317 | GHS07 |
| Hazardous to the aquatic environment - acute GHS chapter 4.1 | Category 1 | H400 | GHS09 |
| Hazardous to the aquatic environment - chronic GHS chapter 4.1 | Category 1 | H410 | GHS09 |
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.

Safety Data Sheet
Getting an SDS for Dicofol
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 Dicofol 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
Dicofol precautionary statements
CLP Annex VI assigns 16 precautionary statements to Dicofol. 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
Dicofol 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.

Dicofol carcinogenicity classification
Under the conditions of this bioassay, technical-grade dicofol was carcinogenic in male B6C3F1 mice, causing hepatocellular carcinomas. No evidence for carcinogenicity was obtained for this compound in Osborne-Mendel rats of either sex or in female B6C3F1 mice.

Cancer Classification: Group C Possible Human Carcinogen
Source: Hazardous Substances Data Bank (HSDB)
No data are available in humans. Limited evidence of carcinogenicity in animals. OVERALL EVALUATION: Group 3: The agent is not classifiable as to its carcinogenicity to humans.

An IARC group and a CLP classification answer different questions. IARC judges whether the evidence for cancer in humans is strong enough; CLP Annex VI is the legally binding EU classification. A substance can carry one and not the other.

Dicofol reactivity
DICOFOL is an organochlorine bridged diphenyl. Halogenated aliphatic compounds are moderately or very reactive. Halogenated organics generally become less reactive as more of their hydrogen atoms are replaced with halogen atoms. Halogenated aliphatics are incompatible with strong oxidizing and reducing agents. Also, they are incompatible with many amines, nitrides, azo/diazo compounds, alkali metals, and epoxides. DICOFOL hydrolyzes in alkali. It is slightly corrosive to metals. Contact with steel at elevated temperatures causes formation of toxic gases. (NTP, 1992).

11 · Questions
Dicofol — frequently asked questions
What is the CAS number of Dicofol?
The CAS number of Dicofol is 115-32-2. Its EC number is 204-082-0.
What is the chemical formula of Dicofol?
The molecular formula of Dicofol is C14H9Cl5O and its molecular weight is 370.5 g/mol.
What does a Dicofol label have to show?
Under CLP Annex VI the label for Dicofol carries the pictograms Exclamation mark and Environment and the signal word is Warning.
Is Dicofol flammable?
CLP Annex VI assigns Dicofol 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 193 °C (379.4 °F), open cup (HSDB).
Is Dicofol a carcinogen?
CLP Annex VI records no harmonised carcinogenicity classification for Dicofol. 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. IARC places it in Group 3: not classifiable as to its carcinogenicity to humans.
What is the boiling point of Dicofol?
The boiling point reported for Dicofol is 225 °C (437 °F), at 760 mmHg (CAMEO).
What is the melting point of Dicofol?
The melting point reported for Dicofol is 77.5 °C (171.5 °F) (HSDB).
How should Dicofol be stored?
Store above 40 °F, away from feed, foodstuffs, or any body of water. (Hazardous Substances Data Bank (HSDB))
