paranitrocresol

Paranitrocresol, also known as 4-nitrocresol or p-nitrocresol, is an organic compound with the chemical formula C7H7NO3. It is a derivative of cresol, a methylphenol, with a nitro group (NO2) attached to the para position of the benzene ring. This compound exists as yellow crystalline solid.

Paranitrocresol is sparingly soluble in water but more soluble in organic solvents like ethanol and ether. Its properties are influenced by the presence of both the hydroxyl group (OH) and the nitro group on the aromatic ring. The nitro group is an electron-withdrawing group, which affects the acidity of the phenolic hydroxyl group.

Industrially, paranitrocresol can be synthesized through the nitration of cresol. It has found applications as an intermediate in the synthesis of dyes, pigments, and certain pharmaceuticals. Its chemical reactivity makes it a useful building block for more complex organic molecules. It is important to handle paranitrocresol with care, as it can be irritating and toxic. Safety precautions should be observed when working with this substance, including appropriate ventilation and personal protective equipment.
