03 · GHS classification
2-(Methylamino)ethanol hazard classification
Harmonised classification under CLP Annex VI. This is the legally binding classification in the EU; other jurisdictions may differ.
2-(Methylamino)ethanol pictograms and signal word
2-(Methylamino)ethanol hazard class and category
| Hazard class | Category | From code | Pictogram |
|---|---|---|---|
| Acute toxicity - oral GHS chapter 3.1 | Category 4 | H302 | GHS07 |
| Acute toxicity - dermal GHS chapter 3.1 | Category 4 | H312 | GHS07 |
| Skin corrosion/irritation GHS chapter 3.2 | Category 1A or 1B or 1C | H314 | GHS05 |
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.
2-(Methylamino)ethanol hazard statements (H-codes)
| Code | Hazard statement |

Safety Data Sheet
Getting an SDS for 2-(Methylamino)ethanol
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-(Methylamino)ethanol 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-(Methylamino)ethanol precautionary statements
CLP Annex VI assigns 10 precautionary statements to 2-(Methylamino)ethanol. 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.
Response
What to do once exposure, spillage or fire has already happened.

05 · Names in the regulation
2-(Methylamino)ethanol 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-(Methylamino)ethanol reactivity
METHYLETHANOLAMINE is an aminoalcohol. Amines are chemical bases. They neutralize acids to form salts plus water. These acid-base reactions are exothermic. The amount of heat that is evolved per mole of amine in a neutralization is largely independent of the strength of the amine as a base. Amines may be incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides. Flammable gaseous hydrogen is generated by amines in combination with strong reducing agents, such as hydrides. This compound may react with oxidizing materials. (NTP, 1992)

12 · Questions
2-(Methylamino)ethanol — frequently asked questions
What is the CAS number of 2-(Methylamino)ethanol?
The CAS number of 2-(Methylamino)ethanol is 109-83-1. Its EC number is 203-710-0.
What is the chemical formula of 2-(Methylamino)ethanol?
The molecular formula of 2-(Methylamino)ethanol is C3H9NO and its molecular weight is 75.11 g/mol.
What does a 2-(Methylamino)ethanol label have to show?
Under CLP Annex VI the label for 2-(Methylamino)ethanol carries the pictograms Corrosion and Exclamation mark and the signal word is Danger.
Is 2-(Methylamino)ethanol flammable?
CLP Annex VI assigns 2-(Methylamino)ethanol 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 76 °C (168.8 °F) (HSDB).
Is 2-(Methylamino)ethanol a carcinogen?
CLP Annex VI records no harmonised carcinogenicity classification for 2-(Methylamino)ethanol. 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 2-(Methylamino)ethanol?
The boiling point reported for 2-(Methylamino)ethanol is 1559 °C (2838.6 °F) (HSDB).
What is the melting point of 2-(Methylamino)ethanol?
The melting point reported for 2-(Methylamino)ethanol is -3 °C (26.6 °F) (HSDB).
How should 2-(Methylamino)ethanol be stored?
Keep container tightly closed in a dry and well-ventilated place. Containers which are opened must be carefully resealed and kept upright to prevent leakage. Storage class (TRGS 510): Combustible, corrosive hazardous materials. (Hazardous Substances Data Bank (HSDB))
