Safety Data Sheet

Getting an SDS for Chlorfenapyr

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 Chlorfenapyr 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

Chlorfenapyr precautionary statements

CLP Annex VI assigns 11 precautionary statements to Chlorfenapyr. 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.

05 · Names in the regulation

Chlorfenapyr 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.

Chlorfenapyr hazard summary

A moderate eye irritant; [HSDB] The active metabolite uncouples oxidative phosphorylation in the mitochondria causing cellular death; [Reference #1] In high-dose animal studies, causes liver changes, depressed activity and ataxia; [RTECS] A mild skin and eye irritant based on animal studies; [MSDSonline]

Chlorfenapyr carcinogenicity classification

Cancer Classification: Suggestive Evidence of Carcinogenicity, but Not Sufficient to Assess Human Carcinogenic Potential

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.

Chlorfenapyr — frequently asked questions

What is the CAS number of Chlorfenapyr?

The CAS number of Chlorfenapyr is 122453-73-0.

What is the chemical formula of Chlorfenapyr?

The molecular formula of Chlorfenapyr is C15H11BrClF3N2O and its molecular weight is 407.61 g/mol.

What does a Chlorfenapyr label have to show?

Under CLP Annex VI the label for Chlorfenapyr carries the pictograms Skull and crossbones and Environment and the signal word is Danger.

Is Chlorfenapyr flammable?

CLP Annex VI assigns Chlorfenapyr 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 Chlorfenapyr a carcinogen?

CLP Annex VI records no harmonised carcinogenicity classification for Chlorfenapyr. 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 melting point of Chlorfenapyr?

The melting point reported for Chlorfenapyr is 100.5 °C (212.9 °F), range, midpoint shown (HSDB).

How should Chlorfenapyr be stored?

Do not store below 32 °F. ... Store in a secure, dry, ventilated area away from children, livestock, and food. Do not store in direct sunlight or heat. (Hazardous Substances Data Bank (HSDB))
