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

Methoxyacetic Acid hazard class and category

GHS hazard classes Methoxyacetic Acid falls into
Hazard class Category From code Pictogram
Acute toxicity - oral GHS chapter 3.1 Category 4 H302 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.

Safety Data Sheet

Getting an SDS for Methoxyacetic Acid

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 Methoxyacetic Acid 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

Methoxyacetic Acid precautionary statements

CLP Annex VI assigns 8 precautionary statements to Methoxyacetic Acid. 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

Methoxyacetic Acid 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.

10 · Questions

Methoxyacetic Acid — frequently asked questions

What is the CAS number of Methoxyacetic Acid?

The CAS number of Methoxyacetic Acid is 625-45-6. Its EC number is 210-894-6.

What does a Methoxyacetic Acid label have to show?

Under CLP Annex VI the label for Methoxyacetic Acid carries the pictograms Health hazard, Corrosion and Exclamation mark and the signal word is Danger.

Is Methoxyacetic Acid flammable?

CLP Annex VI assigns Methoxyacetic Acid 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 112.78 °C (235 °F), above this value (CAMEO).

Is Methoxyacetic Acid a carcinogen?

CLP Annex VI records no harmonised carcinogenicity classification for Methoxyacetic Acid. 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 Methoxyacetic Acid?

The boiling point reported for Methoxyacetic Acid is 203.33 °C (398 °F), range, midpoint shown, at 760 mmHg (CAMEO).

What is the melting point of Methoxyacetic Acid?

The melting point reported for Methoxyacetic Acid is 7.72 °C (45.9 °F) (CAMEO).
