'''Ethyl propiolate''' is an [[organic compound]] with the formula HC<sub>2</sub>CO<sub>2</sub>C<sub>2</sub>H<sub>5</sub>. It is the [[Ethyl group|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.<ref>{{cite journal|title=α-Unsubstituted γ,δ-Unsaturated Aldehydes by Claisen Rearrangement: 3-phenyl-4-pentenal |author=Dennis E.
