Chemical compound

Ethyl propiolate is an organic compound with the formula HC2CO2C2H5. It is the ethyl ester of propiolic acid, the simplest acetylenic carboxylic acid. It is a colorless liquid that is miscible with organic solvents. The compound is a reagent and building block for the synthesis of other organic compounds, reactions that exploit the electrophilicity of the alkyne group.[1]
