Safety Data Sheet

Getting an SDS for Ketoconazole

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 Ketoconazole 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

Ketoconazole precautionary statements

CLP Annex VI assigns 9 precautionary statements to Ketoconazole. 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.

Disposal

05 · Names in the regulation

Ketoconazole 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.

What is the chemical formula of Ketoconazole?

The molecular formula of Ketoconazole is C26H28Cl2N4O4 and its molecular weight is 531.4 g/mol.

What does a Ketoconazole label have to show?

Under CLP Annex VI the label for Ketoconazole carries the pictograms Skull and crossbones, Health hazard and Environment and the signal word is Danger.

Is Ketoconazole flammable?

CLP Annex VI assigns Ketoconazole 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 Ketoconazole a carcinogen?

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

The melting point reported for Ketoconazole is 146 °C (294.8 °F) (HSDB).

How should Ketoconazole be stored?

Store at controlled room temperature 15 deg - 25 °C (59 deg - 77 °F). Protect from moisture. (Hazardous Substances Data Bank (HSDB))
