Reactivity Alerts	Highly Flammable
Reactivity Profile	METHACRYLOYL CHLORIDE is incompatible with strong oxidizing agents, alcohols, bases (including amines). Can polymerize violentlybut the polymerization reaction can be inhibited by the addition of phenolthiazine. May react vigorously or explosively if mixed with diisopropyl ether or other ethers in the presence of trace amounts of metal salts [J. Haz. Mat., 1981, 4, 291].
