3-(Bromomethyl)benzenesulfonamide(CAS: 220798-52-7)

3-(Bromomethyl)benzenesulfonamide (CAS: 220798-52-7) is a white crystalline solid with a molecular weight of approximately 277.03 g/mol. It has low water solubility but good solubility in organic solvents like methanol and dimethylformamide. This compound is relatively unreactive under normal conditions but can undergo bromination and sulfonation reactions. It is stable in air and light but should be stored in a cool, dark place to maintain its integrity.

3-(Bromomethyl)benzenesulfonamide (CAS: 220798-52-7) is typically synthesized via bromination of 3-(hydroxymethyl)benzenesulfonamide followed by sulfonation. This involves treating 3-(hydroxymethyl)benzenesulfonamide with N-bromosuccinimide (NBS) in the presence of a photosensitizer to generate the bromomethyl intermediate, which is then sulfonated with sulfur trioxide pyridine complex (SPC) under mild conditions. The yield is around 70-80%.

3-(Bromomethyl)benzenesulfonamide (CAS: 220798-52-7) finds applications in the pharmaceutical industry for synthesizing certain drugs, as well as in the polymer industry for modifying polymer properties. It also plays a role in the development of sensors and semiconductors, where its unique chemical properties make it suitable for functionalization and modification processes.

When handling 3-(Bromomethyl)benzenesulfonamide (CAS: 220798-52-7), it is essential to wear appropriate personal protective equipment (PPE) such as gloves, goggles, and a lab coat. Work should be conducted in a well-ventilated area or a fume hood. Spills should be cleaned up immediately using appropriate absorbent materials, and the area should be flushed with water. Always consult the Material Safety Data Sheet (MSDS) for detailed safety information and emergency response procedures.
