Product overview & key benefits
Methallyl alcohol (2-methyl-2-propen-1-ol) is an unsaturated primary alcohol. Its largest use is ethoxylation to methallyl polyoxyethylene ether (HPEG), the macromonomer for polycarboxylate superplasticizers in concrete. It is also an intermediate for fragrance and pharmaceutical chemicals, for methallyl esters and ethers, and for specialty resins.
The current page lists the CAS number in the formula field; the correct formula is C₄H₈O.
Reactive double bond and OH
Copolymerizes through the double bond and reacts through the hydroxyl, for esters, ethers and resins.
Specified on your terms
We quote against your purity, water and impurity limits and send the batch COA for each lot.

Selection & comparison
Choosing the right methallyl alcohol grade
| Your requirement | What usually works |
|---|---|
| HPEG / superplasticizer macromonomer | Specify purity and water for ethoxylation |
| Fragrance and pharmaceutical synthesis | Specify impurity limits your QA approves |
| Resin modification | Standard grade |
| Replacing an existing supplier | Send your current TDS or COA; we quote against the parameters you approve |
Packaging & storage
Packaging
167 kg drums.
Storage
Keep drums closed in a cool, ventilated store away from heat and ignition sources.
Transport
Flammable liquid (UN 2614, Class 3, PG III).
From first email to approved supply
Name the end use
HPEG, fine chemicals or resins: purity and water limits follow from it.
Compare the numbers that matter
Purity, water and the impurities that affect your catalyst or reaction.
Protect the material
Keep drums closed and dry; water affects ethoxylation catalysts.
Trial, then lock the spec
Run a sample in your own process and keep the approved lot COA as the reference for contract limits.
