Description:
Benzoic acid, 2-[2-(2-hydroxy-3,6-disulfo-1-naphthalenyl)diazenyl]-, sodium salt (1:3), commonly referred to as a sodium salt of a diazo compound, is characterized by its complex structure that includes a naphthalene moiety with multiple sulfonic acid groups and a hydroxyl group. This compound typically exhibits high solubility in water due to the presence of the sulfonate groups, which enhance its ionic character. It is often used in various applications, including as a dye or pigment in textiles and as a reagent in chemical synthesis. The presence of the diazo group contributes to its reactivity, making it useful in coupling reactions. Additionally, the sulfonic acid groups impart acidic properties, which can influence its behavior in different pH environments. Overall, this compound is notable for its potential applications in both industrial and research settings, particularly in fields related to organic chemistry and materials science.
