Benzenesulfonic acid, 4-amino-, sodium salt, hydrate (1:1:2)

Description:
Benzenesulfonic acid, 4-amino-, sodium salt, hydrate (1:1:2), commonly referred to as sodium 4-aminobenzenesulfonate, is an organic compound characterized by the presence of an amino group and a sulfonic 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 exhibits properties such as being hygroscopic, meaning it can absorb moisture from the environment. The presence of the amino group allows it to participate in various chemical reactions, making it useful in the synthesis of dyes, pharmaceuticals, and as a reagent in organic chemistry. Additionally, its sulfonic acid group imparts strong acidic properties, which can influence its reactivity and interactions in different chemical environments. As a hydrate, it contains water molecules in its crystalline structure, which can affect its stability and solubility. Overall, this compound is significant in both industrial applications and research settings.
