Industrial Uses

1. Pharmaceuticals

  • Treatment of ulcerative colitis: Sulfasalazine is indicated for the treatment of chronic inflammatory diseases such as rheumatoid arthritis in children and adults and ulcerative colitis. It also has off-label uses in treating patients with ankylosing spondylitis, mild to moderately active Crohn disease, psoriasis, and psoriatic arthritis.

2. Performance Chemicals

  • Sulfapyridine Synthesis: Sulfapyridine, a key component of sulfasalazine, is itself a sulfonamide drug. Its synthesis involves reacting 4-acetylaminobenzenesulfonyl chloride with 2-amino-4-methylpyrimidine. 
  • Azo Coupling: Sulfasalazine is synthesized by reacting sulfapyridine with salicylic acid through an azo coupling reaction. This reaction involves converting sulfapyridine into a diazonium salt and then coupling it with salicylic acid in an alkaline medium.
