| Reactivity Profile | METHYL 2-CHLOROPROPIONATE is a halogenated ester. Reacts with acids to liberate heat along with alcohols and acids. Strong oxidizing acids may cause a vigorous reaction that is sufficiently exothermic to ignite the reaction products. Reacts exothermically with bases. Flammable hydrogen is generated with alkali metals and hydrides. |
Anwendungen & Verwendung
Verwenden
Methyl 2-chloropropionate is used as initiator during the synthesis of acrylamide homopolymers and acrylamide-N-isopropylacrylamide block copolymers. It is also used to produce 2-thiophen-2-yl-propionic acid methyl ester.
