In the vast toolkit of organic chemistry, certain molecules emerge as particularly versatile and indispensable. Methyl Vinyl Sulfone (MVS), identified by its CAS number 3680-02-2, is one such compound. Its unique combination of functional groups – a reactive vinyl moiety and an electron-withdrawing sulfone group – makes it a potent building block for a wide array of chemical syntheses. This article delves into the properties and applications of Methyl Vinyl Sulfone, highlighting its significance for researchers and industrial chemists.

Methyl Vinyl Sulfone possesses the molecular formula C3H6O2S and a molecular weight of approximately 106.14 g/mol. It typically presents as a clear, colorless to slightly yellow liquid, with a boiling point around 115-117°C at 19 mmHg. Its physical state and chemical structure are key to its reactivity, enabling it to undergo various addition and substitution reactions.

The primary mode of reactivity for Methyl Vinyl Sulfone is its behavior as a potent Michael acceptor. The electron-withdrawing nature of the sulfone group strongly polarizes the adjacent double bond, rendering the beta-carbon highly susceptible to nucleophilic attack. This makes MVS an excellent substrate for reactions with nucleophiles such as thiols, amines, and carbanions. These reactions are fundamental in constructing carbon-carbon and carbon-heteroatom bonds, essential for building complex organic molecules.

Another critical application of Methyl Vinyl Sulfone is its participation in palladium-catalyzed coupling reactions, notably the Heck reaction. This reaction allows for the direct vinylation of aryl or vinyl halides, providing a powerful method for forming new carbon-carbon bonds. The ability to efficiently introduce a vinyl group or a vinyl sulfone fragment into various molecular frameworks is highly valued in the synthesis of pharmaceuticals, agrochemicals, and advanced materials.

The demand for Methyl Vinyl Sulfone stems from its diverse applications. It serves as a crucial intermediate in the pharmaceutical industry for the synthesis of active pharmaceutical ingredients (APIs). In materials science, it can be polymerized or incorporated into polymer chains to create materials with enhanced thermal and chemical resistance properties. Its use as a derivatization reagent in analytical chemistry further underscores its versatility.

For chemists and formulators looking to purchase Methyl Vinyl Sulfone (CAS 3680-02-2), engaging with reputable manufacturers and suppliers is key. Ensuring product purity, consistent quality, and reliable delivery is vital for successful research and production outcomes. Manufacturers in China are a significant source, often offering competitive pricing and a range of purity grades. Always request detailed specifications and safety data (MSDS) when procuring this versatile chemical intermediate.
