General description
2-Methoxy-4-nitroaniline is an important inducer of CYP1A2 owing to its small molecular size.
Application
2-Methoxy-4-nitroaniline is used as a photometric reagent for the determination of ethinylestradiol (ETE), a semi-synthetic estrogen that is widely used in oral contraceptives.
Biochem/physiol Actions
The metabolism of 2-methoxy-4-nitroaniline (MNA) occurs via the hydroxylation of the phenyl ring to form 6-hydroxy MNA in Harlan Sprague Dawley rats and B6C3F(1)/N mice.
