Used in pharmaceutical research as a key intermediate in the synthesis of sulfa-based drugs, particularly in the development of anti-inflammatory and carbonic anhydrase inhibitor compounds. Its structure allows for strong binding to enzyme active sites, making it valuable in designing treatments for glaucoma and epilepsy. Also explored in the creation of water-soluble prodrugs due to its carboxylic acid group, which enhances bioavailability. Additionally, it serves as a building block in medicinal chemistry for modifying pharmacokinetic properties of drug candidates.
