CAS 78-85-3

Methacrolein

Description:

Methacrolein, with the CAS number 78-85-3, is an organic compound classified as an α,β-unsaturated aldehyde. It is a colorless to pale yellow liquid with a characteristic pungent odor. Methacrolein is soluble in water and exhibits a moderate volatility, making it a reactive substance. Its molecular formula is C4H6O, and it has a molecular weight of approximately 70.1 g/mol. The compound is known for its ability to undergo various chemical reactions, including polymerization and condensation, due to the presence of both the aldehyde functional group and the double bond in its structure. Methacrolein is primarily used in the production of polymers, resins, and as an intermediate in organic synthesis. It is also utilized in the manufacture of flavoring agents and fragrances. However, it is important to handle methacrolein with care, as it can be irritating to the skin, eyes, and respiratory system, and is considered a hazardous substance. Proper safety measures should be taken when working with this compound.

Methacrolein

CAS: 78-85-3

Methacrolein is a reactive organic compound that is formed when methanol reacts with an acid. Methacrolein can be used as an oxidation catalyst to produce acids from alcohols and water. It has been shown to be more efficient than platinum, molybdenum, or zirconium oxide in this reaction. Methacrolein is also a useful reagent for analytical methods because it reacts with hydrogen peroxide to produce the highly fluorescent molecule methacryloyl peroxide. The reaction mechanism of methacrolein formation has been found to involve an intramolecular hydrogen transfer from the methyl group to the ethyl group on the carbonyl carbon atom.
