Sodium p-aminobenzenesulfonate

Description:
Sodium p-aminobenzenesulfonate, with the CAS number 515-74-2, is an organic compound that belongs to the class of sulfonic acids and their salts. It is characterized by the presence of a sulfonate group (-SO3Na) attached to a p-aminobenzene structure, which contributes to its solubility in water. This compound typically appears as a white to light yellow crystalline powder and is known for its hygroscopic nature. Sodium p-aminobenzenesulfonate is often used as a reagent in various chemical reactions, particularly in the synthesis of dyes and pharmaceuticals. It exhibits properties such as being a mild reducing agent and can participate in electrophilic aromatic substitution reactions due to the amino group. Additionally, it has applications in the textile industry as a dyeing auxiliary and in the formulation of surfactants. Safety data indicates that it should be handled with care, as with many chemical substances, to avoid potential irritation or adverse reactions.
