Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of sulfonamide-based drugs with antimicrobial and anti-inflammatory properties. It plays a role in creating compounds that modulate enzyme activity, such as carbonic anhydrase inhibitors used in treating glaucoma and epilepsy. Its structure allows for easy functionalization, making it valuable in medicinal chemistry for designing bioactive molecules. Also employed in the preparation of specialty chemicals and agrochemicals due to its stability and reactivity profile.
