1methoxy4nitrobenzene

1-Methoxy-4-nitrobenzene, also known as p-nitroanisole, is an organic compound with the chemical formula C7H7NO3. It is a pale yellow crystalline solid at room temperature. The molecule consists of a benzene ring substituted with a methoxy group (–OCH3) and a nitro group (–NO2) in a para position relative to each other.

This compound is typically synthesized by the nitration of anisole. It is an important intermediate in the synthesis of various dyes, pharmaceuticals, and agrochemicals. For instance, it can be reduced to p-anisidine, a precursor for azo dyes. The presence of the nitro group makes it susceptible to nucleophilic aromatic substitution reactions under certain conditions, though the methoxy group is activating.

1-Methoxy-4-nitrobenzene is sparingly soluble in water but soluble in common organic solvents such as ethanol, ether, and acetone. Its physical properties include a melting point of around 52-54 °C and a boiling point of approximately 277 °C. Safety precautions should be taken when handling this chemical, as it can be irritating to the skin, eyes, and respiratory tract. It is generally considered moderately toxic.
