2-ETHYLPYRROLE Chemical Properties,Usage,Production

Chemical Properties

clear yellow liquid

Uses

2-Ethylpyrrole may be used in the preparation of 1-(3-methoxyphenyl)-2-ethylpyrrole.

General Description

2-Ethylpyrrole is a monosubstituted alkyl pyrrole. Stochastic, Rothemund-type condensation of pyrrole, 2-ethylpyrrole and arylaldehyde yields 3-ethyl-substituted inverted porphyrin, which readily converts to 3-(1′-hydroxyethyl)- and 3-acetyl-inverted porphyrins. 2-Ethylpyrrole is a conjugated five-membered heterocyclic flavor compound and its photooxidation reactivity was investigated.
