3-Nitrobenzenesulfonic acid

Description:
3-Nitrobenzenesulfonic acid is an aromatic sulfonic acid characterized by the presence of both a nitro group and a sulfonic acid group attached to a benzene ring. Its molecular formula is C6H6N2O4S, and it features a sulfonic acid (-SO3H) group that imparts strong acidity, making it soluble in water and polar solvents. The nitro group (-NO2) is an electron-withdrawing substituent, which influences the reactivity of the compound, particularly in electrophilic aromatic substitution reactions. This compound is typically a yellow to brown solid and is used in various applications, including as an intermediate in the synthesis of dyes, pharmaceuticals, and other organic compounds. It is important to handle 3-nitrobenzenesulfonic acid with care, as it can be harmful if ingested or inhaled, and appropriate safety measures should be taken to avoid exposure. Additionally, it is classified as a hazardous substance, necessitating proper storage and disposal practices in laboratory and industrial settings.
