03 · GHS classification

Quintozene hazard classification

Harmonised classification under CLP Annex VI. This is the legally binding classification in the EU; other jurisdictions may differ.

Quintozene hazard class and category

GHS hazard classes Quintozene falls into
Hazard class Category From code Pictogram
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 Quintozene

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 Quintozene 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

Quintozene precautionary statements

CLP Annex VI assigns 8 precautionary statements to Quintozene. 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.

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

Quintozene 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.

07 · Health hazards

Quintozene health hazards and exposure limits

Quintozene hazard summary

Occupational exposure may occur in workers engaged in the manufacture, formulation, and application of pentachloronitrobenzene. Conjunctivitis with corneal injury has been reported in humans when pentachloronitrobenzene was splashed into the eye. No information is available on the chronic (long- term), reproductive, developmental, or carcinogenic effects of pentachloronitrobenzene in humans. Chronic exposure of dogs to pentachloronitrobenzene in their diet has been observed to result in damage to the liver. Renal agenesis (failure of the kidney to develop), cleft palate, and increased fetal mortality were observed in the offspring of orally exposed mice. Hepatomas were observed in mice exposed to pentachloronitrobenzene via gavage (experimentally placing the chemical in the stomach). EPA has classified pentachloronitrobenzene as a Group C, possible human carcinogen.

Quintozene carcinogenicity classification

IARC classification Group 3 — Not classifiable as to its carcinogenicity to humans
IARC monographs Volume 5: (1974) Some Organochlorine Pesticides

Studied by the US National Toxicology Program: TR-325: Toxicology and Carcinogenesis Studies of Pentachloronitrobenzene (CASRN 82-68-8) in B6C3F1 Mice (Feed Studies) (1987 )

Cancer Classification: Group C Possible Human Carcinogen

Source: Hazardous Substances Data Bank (HSDB)

Classification of carcinogenicity: 1) evidence in humans: no data; 2) evidence in animals: limited. Overall summary evaluation of carcinogenic risk to humans is Group 3: The agent is not classifiable as to its carcinogenicity to humans. /From table/

Source: Hazardous Substances Data Bank (HSDB)

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.

What does a Quintozene label have to show?

Under CLP Annex VI the label for Quintozene carries the pictograms Exclamation mark and Environment and the signal word is Warning.

Is Quintozene flammable?

CLP Annex VI assigns Quintozene 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.

Is Quintozene a carcinogen?

CLP Annex VI records no harmonised carcinogenicity classification for Quintozene. 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 Quintozene?

The boiling point reported for Quintozene is 328 °C (622.4 °F) (ICSC).

What is the melting point of Quintozene?
