Celecoxib Impurities and Celecoxib 

Daicel Pharma synthesizes high-quality Celecoxib impurities, 4-(5-(4-(hydroperoxymethyl)phenyl)-3-(trifluoromethyl)-1H-pyrazol-1-yl)benzenesulfonamide and Celecoxib Hydroxy impurity, which are crucial in the analysis of the quality, stability, and biological safety of the active pharmaceutical ingredient Celecoxib. Moreover, Daicel Pharma offers custom synthesis of Celecoxib impurities and delivers them globally.

Celecoxib [CAS: 169590-42-5] is a medicine that belongs to the group of nonsteroidal anti-inflammatory drugs (NSAIDs). It is a diaryl-substituted pyrazole.

Celecoxib: Use and Commercial Availability  

Celecoxib is a medicine to relieve symptoms in adults with osteoarthritis and rheumatoid arthritis. It treats acute from various sources, like ankylosing spondylitis, juvenile rheumatoid arthritis, and dysmenorrhea. It is available under brand names such as Celebrex, Elyxyb, Consensi, and Seglentis.

Celecoxib Structure and Mechanism of Action

The chemical name of Celecoxib is 4-[5-(4-Methylphenyl)-3-(trifluoromethyl)-1H-pyrazol-1-yl]benzenesulfonamide. Its chemical formula is C₁₇H₁₄F₃N₃O₂S, and its molecular weight is approximately 381.4 g/mol.

Celecoxib has anti-inflammatory and analgesic properties. It is due to the inhibition of prostaglandin synthesis via cyclo-oxygenase-2 (COX-2) inhibition, used in treating arthritis.

Celecoxib Impurities and Synthesis

The impurities formed during the manufacturing¹ of Celecoxib include related substances, degradants, and enantiomeric. These impurities form during the synthesis, isolation, purification, and storage of the drug substance. Various factors like reaction conditions, starting materials, and raw materials influence the formation of impurities. Controlling and minimizing the Celecoxib impurities is critical to ensure its quality and safety for patients.

Daicel offers a Certificate of Analysis (CoA) from a cGMP-compliant analytical facility for Celecoxib impurity standards, 4-(5-(4-(hydroperoxymethyl) phenyl)-3-(trifluoromethyl)-1H-pyrazol-1-yl)benzenesulfonamide and Celecoxib Hydroxy impurity. The CoA includes complete characterization data, such as 1H NMR, 13C NMR, IR, MASS, and HPLC purity^2,3. We also provide 13C-DEPT and CHN on request. We give a complete characterization report on delivery. Daicel has the technology and expertise to prepare any unknown Celecoxib impurity or degradation product.
