2-Nitrobenzenesulfonic acid

Description:

2-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 C6H5NO3S, indicating the presence of carbon, hydrogen, nitrogen, oxygen, and sulfur. This compound typically appears as a yellow to brown solid and is soluble in water due to the polar nature of the sulfonic acid group. It is known for its acidic properties, with a pKa that reflects its ability to donate protons in solution. 2-Nitrobenzenesulfonic acid is utilized in various applications, including as a reagent in organic synthesis, particularly in the preparation of dyes and pharmaceuticals. Additionally, it serves as an intermediate in the production of other chemical compounds. Safety precautions are necessary when handling this substance, as it can be harmful if ingested or inhaled, and may cause skin and eye irritation. Proper storage and disposal methods should be followed to mitigate environmental impact.

2-Nitrobenzenesulfonic Acid Hydrate

CAS: 80-82-0

2-Nitrobenzenesulfonic acid hydrate (2NBS) is a reactive, sulfonated organic compound that has been used for many years as a precursor for pharmaceuticals. 2NBS reacts with sodium carbonate to form a mixture of nitrobenzenesulfonic acids. This process is known as sulfonation and can be used for biological treatment, such as wastewater treatment. 2NBS is also known to react with styryl dye in an intramolecular hydrogen bond to form the corresponding hydroxyl group. 2NBS also has antiinflammatory activities and has been found to inhibit the inflammatory response in rat models of inflammatory bowel disease.
