Benzenesulfonic acid, 3-[2-(4-amino-3-methoxyphenyl)diazenyl]-, sodium salt (1:1)

Description:

Benzenesulfonic acid, 3-[2-(4-amino-3-methoxyphenyl)diazenyl]-, sodium salt (1:1), commonly referred to as a diazo compound, is characterized by its azo group (-N=N-) which links two aromatic systems. This compound features a sulfonic acid group, which enhances its solubility in water, making it useful in various applications, including dye chemistry and as a reagent in organic synthesis. The presence of the amino and methoxy substituents on the aromatic ring contributes to its reactivity and potential biological activity. The sodium salt form indicates that the sulfonic acid group has been neutralized with sodium, improving its stability and handling properties. This compound may exhibit colorimetric properties due to the conjugated system formed by the azo linkage, making it valuable in dyeing processes and as a pH indicator. Additionally, its structure suggests potential applications in pharmaceuticals and materials science, where azo compounds are often utilized for their vibrant colors and functional properties. Safety data should be consulted, as azo compounds can have varying toxicity profiles.
