Ethyl propargylate (Cat No.: R019945) is an organic compound featuring an ester functional group and a terminal alkyne. Its structure includes a propargyl (HC≡C–CH₂–) moiety bonded to an ethyl ester group (–COOCH₂CH₃), making it a versatile building block in organic synthesis. It is widely used in click chemistry, cross-coupling reactions, and the formation of heterocycles. Ethyl propargylate’s alkyne functionality allows for participation in cycloaddition reactions, such as the Huisgen [3+2] azide-alkyne reaction, making it valuable in pharmaceutical, materials, and chemical biology research.
