Benzenesulfinic acid, 4-amino-, sodium salt (1:1)

Description:

Benzenesulfinic acid, 4-amino-, sodium salt (1:1), also known as sodium 4-aminobenzenesulfinic acid, is an organic compound characterized by the presence of both an amino group and a sulfinic acid group attached to a benzene ring. This compound typically appears as a white to off-white crystalline solid and is soluble in water due to the ionic nature of the sodium salt. It is often used in various applications, including as a reducing agent in organic synthesis and in the dye industry for the production of azo dyes. The presence of the amino group allows for further functionalization, making it a versatile intermediate in chemical synthesis. Additionally, the sulfinic acid group contributes to its reactivity, enabling it to participate in various chemical reactions, such as sulfonation and nucleophilic substitution. Safety data indicates that, like many sulfonic acids, it should be handled with care to avoid skin and eye irritation.
