Ethyl propiolate is used as a precursor in the preparation of substituted anthraquinones and pyrazolo[1,5-a]pyridine, which exhibits anti-inflammatory activity. Further, it is employed in the synthesis of benzene-1,2,3,5-tetracarboxylates promoted by triphenylphosphine. Its halogenated derivatives are used as a substrate for direct, asymmetric alkynylation of cyclic beta-ketoesters using chiral phase-transfer catalysts.

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
