Safety Data Sheet

Getting an SDS for Triasulfuron

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 Triasulfuron 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

Triasulfuron precautionary statements

CLP Annex VI assigns 3 precautionary statements to Triasulfuron. 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

Triasulfuron 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.

The molecular formula of Triasulfuron is C14H16ClN5O5S and its molecular weight is 401.8 g/mol.

What does a Triasulfuron label have to show?

Under CLP Annex VI the label for Triasulfuron carries the pictogram Environment and the signal word is Warning.

Is Triasulfuron flammable?

The melting point reported for Triasulfuron is 186 °C (366.8 °F) (HSDB).

How should Triasulfuron be stored?

Keep container tightly closed in a dry and well-ventilated place. (Hazardous Substances Data Bank (HSDB))
