Safety Data Sheet

Getting an SDS for 2-ethoxyaniline

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 2-ethoxyaniline 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

2-ethoxyaniline precautionary statements

CLP Annex VI assigns 11 precautionary statements to 2-ethoxyaniline. 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

2-ethoxyaniline 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.

2-ethoxyaniline storage and handling

2-ethoxyaniline reactivity

O-PHENETIDINE neutralizes acids in exothermic reactions to form salts plus water. May be incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides. Flammable gaseous hydrogen may be generated in combination with strong reducing agents, such as hydrides.

What does a 2-ethoxyaniline label have to show?

Under CLP Annex VI the label for 2-ethoxyaniline carries the pictograms Skull and crossbones and Health hazard and the signal word is Danger.

Is 2-ethoxyaniline flammable?

CLP Annex VI assigns 2-ethoxyaniline 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 93.33 °C (200 °F), above this value (CAMEO).

Is 2-ethoxyaniline a carcinogen?

CLP Annex VI records no harmonised carcinogenicity classification for 2-ethoxyaniline. 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.
