CAS 3147-53-3

5-(Phenylazo)salicylic acid

Description:

5-(Phenylazo)salicylic acid, with the CAS number 3147-53-3, is an organic compound characterized by the presence of both an azo group (-N=N-) and a salicylic acid moiety. This compound typically appears as a solid, often exhibiting a vibrant color due to the azo linkage, which is known for its chromophoric properties. It is soluble in organic solvents and exhibits limited solubility in water, which is common for azo compounds. The presence of the hydroxyl (-OH) group in the salicylic acid structure imparts acidity, allowing it to participate in various chemical reactions, including esterification and complexation with metal ions. 5-(Phenylazo)salicylic acid is often utilized in dye chemistry and as a pH indicator due to its ability to change color in response to pH variations. Additionally, it may have applications in biological studies, particularly in the investigation of azo compounds' effects on living organisms. As with many azo compounds, safety precautions should be taken due to potential toxicity and environmental concerns.

Phenylazosalicylic acid

CAS: 3147-53-3

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.
