Description:
1H-Indole-5-sulfonic acid, 2,3-dihydro-2,3-dioxo-, sodium salt (1:1), with the CAS number 80789-74-8, is a chemical compound characterized by its indole structure, which is a bicyclic compound consisting of a benzene ring fused to a pyrrole ring. This compound features a sulfonic acid group, which enhances its solubility in water and contributes to its acidic properties. The presence of the dioxo functional groups indicates that it has two carbonyl groups, which can participate in various chemical reactions, including nucleophilic attacks. As a sodium salt, it is typically more stable and soluble in aqueous solutions compared to its acid form. This compound may be used in biochemical applications, such as in the synthesis of dyes or as a reagent in organic chemistry. Its properties, including solubility, reactivity, and stability, make it a valuable compound in research and industrial applications. Safety data should be consulted for handling and usage, as with all chemical substances.
