Safety Data Sheet

Getting an SDS for Pindone

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 Pindone 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

Pindone precautionary statements

CLP Annex VI assigns 9 precautionary statements to Pindone. 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

Pindone 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.

Pindone reactivity

Ketones, such as PINDONE, are reactive with many acids and bases liberating heat and flammable gases (e.g., H2). The amount of heat may be sufficient to start a fire in the unreacted portion of the ketone. Ketones react with reducing agents such as hydrides, alkali metals, and nitrides to produce flammable gas (H2) and heat. Ketones are incompatible with isocyanates, aldehydes, cyanides, peroxides, and anhydrides. They react violently with aldehydes, HNO3, HNO3 + H2O2, and HClO4.

10 · Questions

Pindone — frequently asked questions

What is the CAS number of Pindone?

The CAS number of Pindone is 83-26-1. Its EC number is 201-462-8.

What does a Pindone label have to show?

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

Is Pindone flammable?

CLP Annex VI assigns Pindone 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 Pindone a carcinogen?

CLP Annex VI records no harmonised carcinogenicity classification for Pindone. 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 exposure limit for Pindone?

The US occupational exposure limit reported for Pindone is 0.1 [mg/m3] (Haz-Map, Information on Hazardous Chemicals and Occupational Diseases). Limits differ by country: the EU sets its own indicative and binding values, and the figure that applies at a given workplace is the one in the local regulation.

What is the boiling point of Pindone?

The boiling point reported for Pindone is 180 °C (356 °F), at 1 mmHg (reduced pressure) (HSDB).

What is the melting point of Pindone?

The melting point reported for Pindone is 110 °C (230 °F) (NIOSH).
