4-Chloro-3-nitrobenzenesulfonic acid

Description:
4-Chloro-3-nitrobenzenesulfonic acid is an aromatic sulfonic acid characterized by the presence of a sulfonic acid group (-SO3H), a nitro group (-NO2), and a chloro substituent (-Cl) on a benzene ring. This compound is typically a yellow to brown solid at room temperature and is soluble in water due to the polar nature of the sulfonic acid group. It exhibits strong acidity, making it a useful reagent in various chemical reactions, particularly in the synthesis of dyes and pharmaceuticals. The presence of both the nitro and chloro groups contributes to its reactivity, allowing for electrophilic substitution reactions. Additionally, 4-chloro-3-nitrobenzenesulfonic acid can act as a sulfonating agent and is often employed in the preparation of sulfonamide compounds. Safety precautions should be taken when handling this substance, as it can be harmful if inhaled or ingested, and may cause skin and eye irritation. Proper storage and disposal methods are essential to mitigate environmental and health risks associated with this chemical.
