2-Nitrobenzenesulfonamide(CAS: 5455-59-4)

2-Nitrobenzenesulfonamide (CAS: 5455-59-4) is a white crystalline solid with a molecular weight of 217.09 g/mol. It has a melting point of 155-157°C and is slightly soluble in water. It exhibits good solubility in common organic solvents like methanol, ethanol, and acetone. This compound is chemically stable but can react with strong bases to form 2-amino-5-nitrobenzenesulfonate. It is used as a reagent in organic synthesis and pharmaceutical industry.

2-Nitrobenzenesulfonamide (CAS: 5455-59-4) is usually synthesized by the reaction of 2-nitrobenzenesulfonyl chloride with ammonia in the presence of a catalyst such as sodium hydroxide. This process involves the nucleophilic attack of ammonia on the sulfonyl chloride group, followed by work-up to obtain the desired amide. The yield and selectivity are typically very good, with high purity products being obtained.

2-Nitrobenzenesulfonamide (CAS: 5455-59-4) is primarily used in the pharmaceutical industry for the synthesis of various drugs and intermediates. It is also used in the polymer industry for the preparation of functionalized polymers. Additionally, it has applications in the sensor industry for the development of chemical sensors and in the semiconductor industry as a dopant.

When handling 2-Nitrobenzenesulfonamide (CAS: 5455-59-4), it is essential to use appropriate personal protective equipment (PPE) such as gloves and safety goggles. This compound should be handled in a well-ventilated area or a fume hood to avoid inhalation. In case of a spill, it should be carefully contained and disposed of according to local regulations.
