CAS 5042-33-1: Benzenesulfonic acid, 4-amino-3-nitro-, sodium salt (1:1)

Description: Benzenesulfonic acid, 4-amino-3-nitro-, sodium salt (1:1), commonly referred to as a sodium salt of an aromatic sulfonic acid, is characterized by its sulfonic acid functional group, which imparts strong acidic properties. The presence of an amino group and a nitro group on the benzene ring contributes to its reactivity and potential applications in various chemical processes. This compound is typically soluble in water due to the ionic nature of the sodium salt, making it useful in aqueous solutions. It exhibits properties such as being a potential intermediate in organic synthesis, particularly in the production of dyes, pharmaceuticals, and agrochemicals. The nitro group can participate in electrophilic substitution reactions, while the amino group can act as a nucleophile. Safety considerations should be taken into account, as nitro compounds can be hazardous and may require careful handling. Overall, this compound serves as an important building block in synthetic organic chemistry, with applications extending to various industrial sectors.
