3-[2-(4-Aminophenyl)diazenyl]benzenesulfonic acid

Description:

3-[2-(4-Aminophenyl)diazenyl]benzenesulfonic acid, also known as Acid Orange 7, is an azo dye characterized by its vibrant orange color and solubility in water. This compound features a diazo group (-N=N-) linked to an aromatic amine, which contributes to its chromophoric properties, making it useful in various dyeing applications. The presence of the sulfonic acid group enhances its solubility in aqueous solutions, facilitating its use in textiles, food, and biological staining. Acid Orange 7 is known for its stability under normal conditions, although it may degrade under extreme pH or light exposure. It is important to note that azo dyes can undergo metabolic reduction in biological systems, potentially releasing aromatic amines, which may pose health risks. Therefore, safety and regulatory considerations are essential when handling this compound. Overall, 3-[2-(4-Aminophenyl)diazenyl]benzenesulfonic acid exemplifies the functional versatility of azo dyes in industrial applications while highlighting the need for careful management due to potential toxicity.
