Used as a key intermediate in the synthesis of celecoxib, a selective COX-2 inhibitor employed in the treatment of inflammation and pain associated with arthritis. Its structure enables high selectivity for the COX-2 enzyme, reducing gastrointestinal side effects commonly seen with non-selective NSAIDs. Also utilized in research for developing new anti-inflammatory and anticancer agents due to its favorable pharmacokinetic properties and ability to modulate cellular pathways involved in disease progression.
