Description

Indomethacin Sodium is the sodium salt form of the well-known non-steroidal anti-inflammatory drug (NSAID) indomethacin. This compound is valued for its enhanced solubility in aqueous systems compared to the free acid form, which is critical for formulating injectable and other pharmaceutical preparations. It is primarily required by pharmaceutical manufacturers and research institutions developing anti-inflammatory, analgesic, and antipyretic medications, as well as for use in biochemical research.

Application

• Pharmaceutical Active Ingredient (API): Core component in the manufacture of prescription medications for inflammation and pain management.
• Injectable Formulations: Used in the development of sterile injectable solutions where high water solubility is essential.
• Research & Development: Serves as a critical reference standard and biochemical tool in pharmacological and pharmacokinetic studies.
• Analytical Testing: Employed as a high-purity standard in quality control laboratories for HPLC, UV, and other analytical methods.
• Veterinary Medicine: Applied in veterinary pharmaceuticals for the treatment of inflammatory conditions in animals.
