Safety Data Sheet

Getting an SDS for Ethyl Nitrate

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 Ethyl Nitrate 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

Ethyl Nitrate precautionary statements

CLP Annex VI assigns 1 precautionary statement to Ethyl Nitrate. 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.

05 · Names in the regulation

Ethyl Nitrate 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.

All 23 language editions of Annex VI carry this entry. Irish is the twenty-fourth official EU language and has no line here for a different reason: no consolidated CLP text has ever been published in Irish, so there is no Irish edition of Annex VI to quote a name from.

10 · Handling and storage

Ethyl Nitrate storage and handling

Ethyl Nitrate reactivity

Organonitrates, such as ETHYL NITRATE, range from slight to strong oxidizing agents. If mixed with reducing agents, including hydrides, sulfides and nitrides, they may begin a vigorous reaction that culminates in a detonation. Nitroalkanes are milder oxidizing agents, but still react violently with reducing agents at higher temperature and pressures. Nitroalkanes react with inorganic bases to form explosive salts. The presence of metal oxides increases the thermal sensitivity of nitroalkanes. Nitroalkanes with more than one nitro group are generally explosive.

11 · Questions

Ethyl Nitrate — frequently asked questions

What is the CAS number of Ethyl Nitrate?

The CAS number of Ethyl Nitrate is 625-58-1. Its EC number is 210-903-3.

What does a Ethyl Nitrate label have to show?

Under CLP Annex VI the label for Ethyl Nitrate carries the pictogram Exploding bomb and the signal word is Danger.

Is Ethyl Nitrate flammable?

CLP Annex VI assigns Ethyl Nitrate 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. The flash point reported for it is 10 °C (50 °F) (HSDB).

Is Ethyl Nitrate a carcinogen?

CLP Annex VI records no harmonised carcinogenicity classification for Ethyl Nitrate. 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 boiling point of Ethyl Nitrate?

The boiling point reported for Ethyl Nitrate is 87.2 °C (189 °F), at 762 mmHg (HSDB).

What is the melting point of Ethyl Nitrate?

The melting point reported for Ethyl Nitrate is -94.6 °C (-138.3 °F) (HSDB).
