CAS 6268-49-1: 4-(4-dimethylaminophenylazo)benzoic acid

Description: 4-(4-Dimethylaminophenylazo)benzoic acid, also known as a type of azo dye, is characterized by its vibrant color and is commonly used in various applications, including textiles and as a pH indicator. This compound features an azo group (-N=N-) linking two aromatic rings, which contributes to its chromophoric properties, resulting in strong absorption of visible light. The presence of the dimethylamino group enhances its solubility in organic solvents and can influence its reactivity and stability. As a benzoic acid derivative, it possesses a carboxylic acid functional group, which can participate in hydrogen bonding and affect its acidity and interactions in solution. The compound is typically synthesized through azo coupling reactions, and its stability can be influenced by pH and the presence of other chemical species. Safety considerations are important, as some azo compounds can be toxic or carcinogenic, necessitating careful handling and disposal. Overall, 4-(4-dimethylaminophenylazo)benzoic acid is notable for its color properties and potential applications in various fields.
