4-CHLORO-3-NITROBENZENESULFONIC ACID, SODIUM SALT(CAS: 17691-19-9)

Sodium 4-chloro-3-nitrobenzenesulfonate (CAS: 17691-19-9) is a white or pale yellow crystalline solid. It has a molecular weight of approximately 320.03 g/mol and is slightly soluble in water. It is known for its high reactivity, particularly towards reducing agents and bases. It decomposes above 150°C and is stable in acidic solutions.

Sodium 4-chloro-3-nitrobenzenesulfonate can be synthesized by reacting 4-chloro-3-nitrobenzenesulfonic acid with sodium hydroxide. Commonly, this involves dissolving the acid in a suitable solvent like water or ethanol, followed by the addition of sodium hydroxide. This process yields a high yield of the compound, typically around 85-90%, with good selectivity.

Sodium 4-chloro-3-nitrobenzenesulfonate (CAS: 17691-19-9) is primarily used in the pharmaceutical industry for the synthesis of certain drugs. It also has applications in the polymer industry as a stabilizer and in the electronics industry, specifically in the production of semiconductors and sensors.

When handling Sodium 4-chloro-3-nitrobenzenesulfonate (CAS: 17691-19-9), it is essential to wear appropriate personal protective equipment (PPE) such as gloves, safety glasses, and a lab coat. Work should be performed in a well-ventilated area or a fume hood. Spills should be handled carefully using absorbent materials, and the area should be cleaned thoroughly. Always consult the Safety Data Sheet (SDS) for detailed handling and storage guidelines.
