Description

Ethyl 2-butynoate is used as a precursor for the synthesis of 3-ethyl, 1-methyl 1-(2-nitrophenyl)-cyclopent-3-ene-1,3-dicarboxylate, alkenylsilanols and tricyclic aziridine derivatives. It acts as a methanogenesis inhibitor. As an electron deficient alkyne derivative, it plays a vital role in the preparation of 1,3-dienes catalyzed by rhodium(I)/H8-BINAP complex.

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.

Applications
Le 2-butynoate d’éthyle est utilisé comme précurseur pour la synthèse du 3-ethyl, 1-methyl 1-(2-nitrophenyl)-cyclopent-3-ene-1,3-dicarboxylate, des alkénylsilanols et des dérivés tricycliques de l’aziridine. Il agit comme un inhibiteur de la méthanogenèse. En tant que dérivé alcyne déficient en électrons, il joue un rôle vital dans la préparation des 1,3-diènes catalysés par le complexe rhodium(I)/H8-BINAP.

Solubilité
Miscible à l’eau, au chloroforme et à l’acétate d’éthyle.

Remarques
Sensible à l’air. Incompatible avec les agents oxydants, les bases et les acides.
