Used in pharmaceutical research as a carbonic anhydrase inhibitor with potential applications in treating glaucoma and certain types of cancer. Shows activity against tumor-associated enzyme isoforms, making it a lead compound in antitumor drug development. Also investigated for diuretic properties due to sulfamoyl group presence. Studied for its ability to cross cell membranes and inhibit intracellular carbonic anhydrase activity, supporting use in hypoxic tumor environments.
