Is Methallyl Alcohol the same material as HPEG polyether monomer?

No. Methallyl Alcohol, CAS 513-42-8, is the small-molecule unsaturated alcohol used as a feedstock. HPEG is a higher-molecular-weight methallyl-alcohol ethoxylate, so confirm which material is required before ordering.

What is Methallyl Alcohol used for?

It is used as an organic intermediate for fragrances, resins, methallyl esters, polyether monomers and specialty unsaturated compounds. The terminal allylic alcohol group makes it useful for building polymerizable derivatives.

What should be confirmed before ordering industrial Methallyl Alcohol?

Confirm GC assay, water, color, appearance and any process-specific impurity limits, then state the intended downstream reaction and required quantity. Because it is an unsaturated alcohol, also confirm inhibitor level and storage stability if needed.

What handling and storage points apply to Methallyl Alcohol?

Store in a closed, clearly labelled flammable-liquid container away from ignition sources and oxidizing agents. Use ventilation, chemical-resistant PPE and bonding/grounding during transfer, and control the storage temperature to limit vapor formation.

How does Methallyl Alcohol differ from Allyl Alcohol?

Methallyl Alcohol is 2-methylprop-2-en-1-ol, while Allyl Alcohol is prop-2-en-1-ol. The methyl substituent in Methallyl Alcohol changes the unsaturated structure and reactivity, so the two should not be substituted without confirming the downstream reaction.

Methallyl Alcohol CAS 513-42-8

Methallyl Alcohol, also known as 2-methyl-2-propen-1-ol, methallyl hydroxide, or isobutenyl alcohol, refers to the same unsaturated alcohol compound. Identified by CAS 513-42-8, it contains both a terminal hydroxyl group and a substituted olefinic bond, enabling participation in esterification and polymer-related reactions. In industrial processing, it is primarily used as an intermediate for polymer modification, where it introduces reactive allylic functionality into downstream resins and specialty chemical intermediates.
