Description

Phenylbutazone Calcium is the calcium salt of the non-steroidal anti-inflammatory drug (NSAID) phenylbutazone. This compound is valued for its anti-inflammatory, analgesic, and antipyretic properties, offering a stable and bioavailable form for specific pharmaceutical formulations. It is primarily utilized by manufacturers in the pharmaceutical and veterinary medicine industries for the development of targeted therapeutic products.

Application

• Pharmaceutical Intermediates: Serves as a key active pharmaceutical ingredient (API) or precursor in the synthesis of anti-inflammatory medications.
• Veterinary Pharmaceuticals: Used in formulations for the treatment of pain, inflammation, and fever in large animals, particularly horses and livestock.
• Research & Development: Employed in biochemical and pharmacological research to study NSAID mechanisms and develop new therapeutic agents.
• Analytical Reference Standards: Functions as a high-purity standard in quality control laboratories for HPLC, LC-MS, or other analytical methods.
• Specialty Chemical Synthesis: Acts as a building block for the synthesis of more complex chemical entities in fine chemical production.
