General description

4-Nitroanisole undergoes photochemical nucleophilic aromatic substitution by hydroxide ion to form 4-methoxyphenol and 4-nitrophenol.

Application

4-Nitroanisole was used as probe to determine Π* of Kamlet-Taft solvent parameters and high pressure and supercritical water in the temperature range of 16-420 °C. 4-Nitroanisole was used as carbon and energy supplement for the isolation of Rhodococcus strains.

Biochem/physiol Actions

4-Nitroanisole is O-demethylated to 4-nitrophenol by human liver microsomes.

1. 4-Nitroanisole is O-demethylated to 4-nitrophenol by human liver microsomes. Kinetic studies indicate that this metabolic route is mediated by two cytochrome P450 isoforms, one with a K(m) = 2.1 microM and the other with a K(m) = 220 microM.
