Methyl propiolate Usage And Synthesis

Chemical Properties	colourless to light yellow liquid
Uses	Methyl propiolate was used in the synthesis of polysubstituted 3-arylaminoacrylate and tetrahydropyrimidin-2-one derivatives. It was also used as a thiol derivatizing agent for capillary electrophoresis.
Purification Methods	Purify the propiolate by fractional distillation and collecting the middle fraction, note that propiolic acid has a high b [144o(dec)/760mm]. [Beilstein 2 IV 1688.] LACHRYMATORY.
