Methacryloyl chloride
Methacryloyl chloride (CAS: 920-46-7) is a highly reactive acyl chloride and a key building block in organic synthesis. Its molecular formula is CH2=C(CH3)COCl, with a molecular weight of 104.53 g/mol. This compound serves as a vital intermediate for introducing the methacryloyl functional group into various molecules, finding significant utility in polymer science and materials research. It is a corrosive and flammable liquid requiring careful handling.
Monomer Synthesis
Methacryloyl chloride is a crucial precursor for synthesising methacrylate monomers. These monomers are widely used in the production of polymers and copolymers for applications such as coatings, adhesives, and dental materials.
Organic Synthesis Intermediate
As a reactive acyl halide, it participates in numerous acylation reactions, enabling the formation of esters, amides, and other derivatives. This makes it a valuable building block in the synthesis of complex organic molecules, including pharmaceuticals and agrochemicals.
Polymer Modification
It can be employed to modify existing polymers, introducing methacryloyl groups that can subsequently be cross-linked or functionalised. This allows for tailoring polymer properties for specific material science applications.
