3-Aminobenzene sulfonic acid

Description:
3-Aminobenzenesulfonic acid, also known as meta-aminobenzenesulfonic acid, is an organic compound characterized by the presence of both an amino group (-NH2) and a sulfonic acid group (-SO3H) attached to a benzene ring. Its molecular formula is C6H7NO3S, and it is typically a white to light yellow crystalline solid. This compound is soluble in water, which enhances its utility in various applications. It is primarily used as an intermediate in the synthesis of dyes, pigments, and pharmaceuticals. The amino group provides basic properties, while the sulfonic acid group imparts acidic characteristics, making it a zwitterionic compound under certain conditions. 3-Aminobenzenesulfonic acid is also known for its role in the production of surfactants and as a reagent in organic synthesis. Safety considerations include handling it with care, as it may cause irritation to the skin and eyes. Proper storage and disposal methods should be followed to mitigate environmental impact.
