:4-Sulfobenzoic acid
Description:
4-Sulfobenzoic acid, also known as para-sulfobenzoic acid, is an aromatic sulfonic acid characterized by the presence of a sulfonic acid group (-SO3H) attached to the para position of a benzoic acid structure. Its molecular formula is C7H6O3S, and it features a benzene ring with a carboxylic acid group (-COOH) and a sulfonic acid group. This compound is typically a white to off-white crystalline solid that is soluble in water due to the polar nature of the sulfonic acid group. It exhibits acidic properties, making it useful in various chemical reactions and applications, including as a reagent in organic synthesis and as an intermediate in the production of dyes and pharmaceuticals. Additionally, 4-sulfobenzoic acid can act as a surfactant and is utilized in analytical chemistry for the determination of certain metal ions. Its stability and reactivity are influenced by the functional groups present, allowing it to participate in electrophilic substitution reactions typical of aromatic compounds.
