Benzoic acid, 2-hydroxy-5-[(4-hydroxyphenyl)azo]-

Description:

Benzoic acid, 2-hydroxy-5-[(4-hydroxyphenyl)azo]- is an organic compound characterized by its azo group, which is a functional group containing a nitrogen-nitrogen double bond (–N=N–). This compound features a benzoic acid moiety, indicating it has a carboxylic acid functional group (-COOH) attached to a benzene ring, along with a hydroxyl group (-OH) and an azo linkage to a para-hydroxyphenyl group. The presence of these functional groups suggests that the compound may exhibit properties such as acidity due to the carboxylic acid, potential for hydrogen bonding from the hydroxyl groups, and chromophoric characteristics due to the azo group, which can impart color. This compound may be used in various applications, including as a dye or pigment in textiles and other materials. Its solubility, stability, and reactivity can be influenced by the presence of the hydroxyl and carboxylic acid groups, making it of interest in both synthetic and analytical chemistry contexts.
