Used primarily in the synthesis of pharmaceuticals, particularly in the development of sulfonamide-based drugs, which are effective as antibiotics and diuretics. It serves as a key intermediate in organic synthesis, enabling the creation of complex molecules with potential therapeutic properties. Additionally, it is utilized in research settings to study enzyme inhibition mechanisms, aiding in the discovery of new drug targets. Its sulfonamide group is crucial for binding to specific proteins, making it valuable in designing compounds for treating bacterial infections and other medical conditions.
