Tenoxicam
Tenoxicam (CAS 59804-37-4), with the molecular formula C13H11N3O4S2 and a molecular weight of 337.37, is a potent non-steroidal anti-inflammatory drug (NSAID) belonging to the oxicam class. It functions as a COX inhibitor, thereby reducing prostaglandin synthesis. Tenoxicam is primarily utilised in pharmaceutical research and as an active pharmaceutical ingredient (API) intermediate for the synthesis of anti-inflammatory and analgesic agents.
- IUPAC
- 4-Hydroxy-2-methyl-N-2-pyridinyl-2H-thieno(2,3-e)-1,2-thiazine-3-carboxamide 1,1-dioxide

Pharmaceutical Intermediate
Utilised in the synthesis pathway for developing active pharmaceutical ingredients (APIs) targeting inflammatory conditions. Its chemical structure serves as a key building block for novel drug candidates.
Research Chemical
Employed in biochemical and pharmacological research to study cyclooxygenase (COX) inhibition mechanisms and prostaglandin synthesis pathways. Supports investigations into inflammatory and pain management processes.
Enzyme Inhibitor Studies
Serves as a valuable tool in enzyme kinetics studies, specifically for understanding the inhibition profiles of COX enzymes. Aids in the development of new therapeutic agents.
