4-[(4-Nitrophenyl)azo]-1,2-benzenediol

Description:

4-[(4-Nitrophenyl)azo]-1,2-benzenediol, also known as 4-nitro-phenylazo-resorcinol, is an organic compound characterized by its azo group (-N=N-) linking a 4-nitrophenyl moiety to a resorcinol structure. This compound typically appears as a solid with a distinct color, often exhibiting shades of red or orange due to the presence of the azo linkage, which is known for its chromophoric properties. It is soluble in organic solvents but has limited solubility in water. The presence of both hydroxyl groups and the nitro group contributes to its reactivity, making it useful in various applications, including as a dye or indicator in analytical chemistry. The compound may also exhibit biological activity, which can be of interest in pharmacological studies. Safety considerations should be taken into account, as nitro compounds can be hazardous and may pose environmental risks. Proper handling and disposal according to safety guidelines are essential when working with this substance.
