Safety Data Sheet
Getting an SDS for 2-(2-methoxyethoxy)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-(2-methoxyethoxy)eth… 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-(2-methoxyethoxy)ethanol precautionary statements
CLP Annex VI assigns 4 precautionary statements to 2-(2-methoxyethoxy)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-(2-methoxyethoxy)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-(2-methoxyethoxy)ethanol reactivity
DIETHYLENE GLYCOL MONOMETHYL ETHER is a ether-alcohol derivative. The ether being relatively unreactive. Flammable and/or toxic gases are generated by the combination of alcohols with alkali metals, nitrides, and strong reducing agents. They react with oxoacids and carboxylic acids to form esters plus water. Oxidizing agents convert alcohols to aldehydes or ketones. Alcohols exhibit both weak acid and weak base behavior. They may initiate the polymerization of isocyanates and epoxides.

What is the CAS number of 2-(2-methoxyethoxy)ethanol?
The CAS number of 2-(2-methoxyethoxy)ethanol is 111-77-3. Its EC number is 203-906-6.
What does a 2-(2-methoxyethoxy)ethanol label have to show?
Under CLP Annex VI the label for 2-(2-methoxyethoxy)ethanol carries the pictogram Health hazard and the signal word is Danger.
Is 2-(2-methoxyethoxy)ethanol flammable?
CLP Annex VI assigns 2-(2-methoxyethoxy)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 96.11 °C (205 °F) (HSDB).
Is 2-(2-methoxyethoxy)ethanol a carcinogen?
CLP Annex VI records no harmonised carcinogenicity classification for 2-(2-methoxyethoxy)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-(2-methoxyethoxy)ethanol?
The boiling point reported for 2-(2-methoxyethoxy)ethanol is 193 °C (379.4 °F) (HSDB).
What is the melting point of 2-(2-methoxyethoxy)ethanol?
The melting point reported for 2-(2-methoxyethoxy)ethanol is -70 °C (-94 °F) (CAMEO).
How should 2-(2-methoxyethoxy)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. Store under inert gas. Hygroscopic. (Hazardous Substances Data Bank (HSDB))
