03 · GHS classification

Harmonised classification under CLP Annex VI. This is the legally binding classification in the EU; other jurisdictions may differ.

Ethyl bromoacetate hazard class and category

GHS hazard classes Ethyl bromoacetate falls into
Hazard class Category From code Pictogram
Acute toxicity - oral GHS chapter 3.1 Category 1 or 2 H300 GHS06
Acute toxicity - dermal GHS chapter 3.1 Category 1 or 2 H310 GHS06
Acute toxicity - inhalation GHS chapter 3.1 Category 1 or 2 H330 GHS06

Where two values are shown with “or”, the hazard statement is shared by more than one category or by more than one class, and the code alone does not say which. H272, for example, belongs to oxidising liquids and to oxidising solids — the physical state decides. The binding answer for a specific entry is in the CLP Annex VI table itself.

Safety Data Sheet

Getting an SDS for Ethyl bromoacetate

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 bromoacetate 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 bromoacetate precautionary statements

CLP Annex VI assigns 10 precautionary statements to Ethyl bromoacetate. 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.

05 · Names in the regulation

Ethyl bromoacetate 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.

Ethyl bromoacetate reactivity

ETHYL BROMOACETATE is a halogenated ester. Esters react with acids to liberate heat along with alcohols and acids. Strong oxidizing acids may cause a vigorous reaction that is sufficiently exothermic to ignite the reaction products. Heat is also generated by the interaction of esters with caustic solutions. Flammable hydrogen is generated by mixing esters with alkali metals and hydrides.

Ethyl bromoacetate UN number and transport classification

Transport classification is a separate system from the GHS classification above. It decides how a package is marked and how a load may be carried; it does not follow from the workplace label, and the workplace label does not follow from it.

What does a Ethyl bromoacetate label have to show?

Under CLP Annex VI the label for Ethyl bromoacetate carries the pictogram Skull and crossbones and the signal word is Danger.

Is Ethyl bromoacetate flammable?

CLP Annex VI assigns Ethyl bromoacetate 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 47.78 °C (118 °F) (HSDB).

Is Ethyl bromoacetate a carcinogen?

CLP Annex VI records no harmonised carcinogenicity classification for Ethyl bromoacetate. 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 bromoacetate?

The boiling point reported for Ethyl bromoacetate is 168.5 °C (335.3 °F) (HSDB).
