Mavacoxib

Mavacoxib is a fluorinated sulfonamide derivative featuring a pyrazole ring fused to a substituted benzene core, with a terminal sulfonyl group linked to a 4-fluorophenyl moiety. Its structure incorporates three trifluoromethyl groups, conferring metabolic stability, and a pyrazole-imidazole hybrid scaffold critical for COX-2 selectivity. As the parent drug, it serves as a direct API for anti-inflammatory formulations. This compound functions as an HPLC reference standard for quantifying mavacoxib in pharmaceutical dosage forms.
