CAS 515-74-2

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.

Sodium 4-aminobenzenesulfonate

CAS: 515-74-2

Sodium 4-aminobenzenesulfonate is a salt of the sulfonate group. It is used as a chemical intermediate in the production of sodium citrate and zirconium oxide. Sodium 4-aminobenzenesulfonate has been shown to be chemically stable and can be used at high temperatures without decomposition. It reacts with sodium carbonate, water vapor, and glycol ethers to produce anhydrous sodium carbonate, hydrogen fluoride, and monosodium 4-aminobenzenesulfonate. The reaction mechanism is similar to that of the reaction between sodium hydroxide and hydrochloric acid. This product also has been shown to have a glomerular filtration rate of 43 ml/minute/1.73m2.
