(2E)-2-Cyano-3-(3-ethoxy-4-hydroxy-5-nitrophenyl)-N,N-diethyl-2-propenamide Chemical Properties,Usage,Production

Uses

(2E)-2-Cyano-3-(3-ethoxy-4-hydroxy-5-nitrophenyl)-N,N-diethyl-2-propenamide is an impurity of Entacapone (E558500), a peripherally acting inhibitor of catechol-O-methyl transferase (COMT), an enzyme involved in the metabolism of catecholamine neurotransmitters and related drugs. Antiparkinsonian.

Definition

ChEBI: 3-O-ethylentacapone is a C-nitro compound that is entacapone in which the phenolic hydroxy group that is meta to the nitro group has been converted into the corresponding ethyl ether. It is a monocarboxylic acid amide, a nitrile, an aromatic ether and a member of 2-nitrophenols. It is functionally related to a 5-nitrovanillin and an entacapone.
