Safety Data Sheet

Getting an SDS for Azoxystrobin

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 Azoxystrobin 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

Azoxystrobin precautionary statements

CLP Annex VI assigns 7 precautionary statements to Azoxystrobin. 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

Azoxystrobin 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.

Azoxystrobin carcinogenicity classification

Cancer Classification: Not Likely to be Carcinogenic to Humans

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.

10 · Questions

Azoxystrobin — frequently asked questions

What is the CAS number of Azoxystrobin?

The CAS number of Azoxystrobin is 131860-33-8.

What is the chemical formula of Azoxystrobin?

The molecular formula of Azoxystrobin is C22H17N3O5 and its molecular weight is 403.4 g/mol.

What does a Azoxystrobin label have to show?

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

Is Azoxystrobin flammable?

Is Azoxystrobin a carcinogen?

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

The melting point reported for Azoxystrobin is 116 °C (240.8 °F) (HSDB).

How should Azoxystrobin be stored?

Store commercial products in a well-ventilated, secure area out of the reach of children and domestic animals. Do not store food, beverages or tabacco in the storage area. (Hazardous Substances Data Bank (HSDB))
