METHACRYLOYL CHLORIDE, with CAS number 920-46-7, is an organic compound that belongs to the class of acyl chlorides. It is used as a reactive intermediate in the synthesis of polymers, resins, and other organic compounds. In particular, it is commonly used in the production of polymethyl methacrylate (PMMA) and other acrylic polymers, as well as in the preparation of methacrylic acid esters and amides. It can also be used as a cross-linking agent in polymer chemistry and as a modifier in the synthesis of specialty polymers. However, it is important to handle methacryloyl chloride with care as it is a highly reactive and corrosive compound that can cause severe burns and respiratory irritation.
