METHACRYLOYL CHLORIDE is incompatible with strong oxidizing agents, alcohols, bases (including amines). Can polymerize violently; but 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].

Releases of CERCLA hazardous substances are subject to the release reporting requirement of CERCLA section 103, codified at 40 CFR part 302, in addition to the requirements of 40 CFR part 355. Methacryloyl chloride is an extremely hazardous substance (EHS) subject to reporting requirements when stored in amounts in excess of its threshold planning quantity (TPQ) of 100 lbs.
