Ketoprofen is a synthetic nonsteroidal anti-inflammatory drug (NSAID) belonging to the propionic acid class. It acts by inhibiting cyclooxygenase (COX) enzymes, reducing prostaglandin synthesis to alleviate pain, inflammation, and fever. Chemically, it is 2-(3-benzoylphenyl)propionic acid with the molecular formula C₁₆H₁₄O₃ and CAS number 22071-15-4. This high-purity grade (≥98% by HPLC) is primarily used as an active pharmaceutical ingredient (API) in the formulation of medications for conditions such as rheumatoid arthritis, osteoarthritis, ankylosing spondylitis, gout, and post-operative pain. It is also employed in research for studying anti-inflammatory mechanisms or as an intermediate in pharmaceutical synthesis. Available forms of the final drug include oral tablets, topical gels/creams, and injectable solutions, but this product is the pure compound suitable for laboratory and industrial applications. Note: As a reagent, it should be handled with care due to potential skin irritation and gastrointestinal risks upon exposure.
