3-Hydroxybenzenesulfonic acid

Description:
3-Hydroxybenzenesulfonic acid, also known as m-hydroxybenzenesulfonic acid, is an aromatic sulfonic acid characterized by the presence of both a hydroxyl group (-OH) and a sulfonic acid group (-SO3H) attached to a benzene ring. This compound is typically a white to light yellow solid that is soluble in water due to the polar nature of its functional groups. 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. The presence of the hydroxyl group allows for further functionalization, enhancing its reactivity. Additionally, 3-hydroxybenzenesulfonic acid can participate in electrophilic aromatic substitution reactions, making it a versatile compound in synthetic organic chemistry. Its CAS number, 585-38-6, is a unique identifier that facilitates its recognition in chemical databases and regulatory frameworks. Safety precautions should be observed when handling this compound, as with many sulfonic acids, due to its corrosive nature.
