CAS 96-75-3

4-Nitroaniline-2-sulfonic acid

Description:

4-Nitroaniline-2-sulfonic acid, also known by its CAS number 96-75-3, is an aromatic sulfonic acid derivative characterized by the presence of both a nitro group and a sulfonic acid group attached to an aniline structure. This compound typically appears as a crystalline solid and is soluble in water due to the sulfonic acid functionality, which enhances its polarity. It exhibits acidic properties, primarily due to the sulfonic acid group, and can participate in various chemical reactions, including electrophilic substitution and nucleophilic attack. The nitro group contributes to its electron-withdrawing characteristics, influencing its reactivity and stability. 4-Nitroaniline-2-sulfonic acid is often used in dye manufacturing, as an intermediate in organic synthesis, and in analytical chemistry as a reagent. Safety considerations include handling it with care, as it may pose health risks upon exposure, including potential carcinogenic effects. Proper storage and disposal methods should be followed to mitigate environmental impact and health hazards.
