Description

Phenylbutazone Sodium is the sodium salt form of the non-steroidal anti-inflammatory drug (NSAID) phenylbutazone, offering enhanced solubility for formulation. This compound is valued for its potent anti-inflammatory, analgesic, and antipyretic properties, making it a critical active pharmaceutical ingredient (API). It is primarily required by manufacturers in the veterinary pharmaceutical and research sectors for developing injectable and oral therapeutic solutions.

Application

• Veterinary Pharmaceuticals: As a key API in formulations for the treatment of musculoskeletal pain, inflammation, and fever in large animals such as horses and cattle.
• Analgesic & Anti-inflammatory Preparations: Used in the development of injectable solutions and oral pastes for effective pain and inflammation management.
• Research & Development: Serves as a reference standard and biochemical tool in pharmacological studies related to cyclooxygenase (COX) inhibition and NSAID mechanisms.
• Pharmaceutical Intermediates: Acts as a crucial synthetic intermediate for further chemical modifications and derivative synthesis in medicinal chemistry.
