Safety Data Sheet

Getting an SDS for Fluroxypyr

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 Fluroxypyr 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

Fluroxypyr precautionary statements

CLP Annex VI assigns 2 precautionary statements to Fluroxypyr. 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.

Disposal

What has to happen to the contents and the empty container.

05 · Names in the regulation

Fluroxypyr 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.

Fluroxypyr carcinogenicity classification

Cancer Classification: Not Likely to be Carcinogenic 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.

What is the CAS number of Fluroxypyr?

The CAS number of Fluroxypyr is 69377-81-7.

What is the chemical formula of Fluroxypyr?

The molecular formula of Fluroxypyr is C7H5Cl2FN2O3 and its molecular weight is 255.03 g/mol.

Is Fluroxypyr flammable?

Is Fluroxypyr a carcinogen?

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

The melting point reported for Fluroxypyr is 232 °C (449.6 °F) (HSDB).

How should Fluroxypyr be stored?

Do not use or store near heat or open flame. (Hazardous Substances Data Bank (HSDB))
