Phenylazosalicylic acid is a crystalline solid that belongs to the group of phenylacetic acids. It is synthesized by the reaction of nitric acid with salicylic acid, which is produced from the distillation of wood. Phenylazosalicylic acid has a molecular weight of 150.09 g/mol and a melting point of 123°C. The molecule is unionized in water and can be found in wastewater effluent at concentrations as high as 3 ppm. This compound has acidic properties and reacts with picric acid to form phenylazosalicylic picrate, which is used for the treatment of anthrax. Phenylazosalicylic acid also shows proton-pumping activity, which may be due to its ability to bind to anionic sites on proteins such as carbonic anhydrase II and H+/K+ ATPase.

2-Hydroxy-5-(phenyldiazenyl)benzoic acid is a useful organic compound for research related to life sciences. The catalog number is T66093 and the CAS number is 3147-53-3.
