Used as a key intermediate in the synthesis of celecoxib, a selective COX-2 inhibitor widely prescribed for its anti-inflammatory, analgesic, and antipyretic effects in conditions like osteoarthritis, rheumatoid arthritis, and acute pain. Its structure enables high selectivity for COX-2 over COX-1, reducing gastrointestinal side effects commonly associated with non-selective NSAIDs. Also serves as a building block in medicinal chemistry for developing new sulfonamide-based bioactive molecules with potential anticancer, antimicrobial, and antidiabetic activities. Employed in research settings to explore structure-activity relationships in pyrazole derivatives.
