3-Sulfobenzoic acid

Description:
3-Sulfobenzoic acid, also known as m-sulfobenzoic acid, is an aromatic sulfonic acid characterized by the presence of a sulfonic acid group (-SO3H) attached to the benzene ring at the meta position relative to the carboxylic acid group (-COOH). This compound is typically a white to off-white crystalline solid that is soluble in water due to the polar nature of its functional groups. It exhibits acidic properties, with the ability to donate protons in solution, making it useful in various chemical applications. 3-Sulfobenzoic acid is often employed as a reagent in organic synthesis, particularly in the preparation of dyes, pharmaceuticals, and other chemical intermediates. Additionally, it can serve as a pH indicator and is utilized in analytical chemistry for the determination of metal ions. Its structural features contribute to its reactivity and solubility, making it a valuable compound in both industrial and laboratory settings. Safety precautions should be observed when handling this substance, as with many chemical reagents.
