Description

Oxaprozin is a non-steroidal anti-inflammatory drug (NSAID) belonging to the propionic acid derivative class. It is valued for its potent anti-inflammatory, analgesic, and antipyretic properties, making it a key active pharmaceutical ingredient (API) in therapeutic formulations. This compound is primarily required by pharmaceutical manufacturers and research institutions developing treatments for conditions such as osteoarthritis, rheumatoid arthritis, and other inflammatory disorders.

Application

• Pharmaceutical API: Primary use as the active ingredient in prescription and generic anti-inflammatory medications.
• Tablet & Capsule Formulation: Incorporated into solid oral dosage forms for the management of chronic pain and inflammation.
• Analgesic Drug Development: Serves as a reference standard and building block in R&D for new analgesic compounds.
• Veterinary Medicine: Potential application in anti-inflammatory treatments for animals.
• Clinical Research: Used in bioavailability, stability, and pharmacokinetic studies.
• Chemical Synthesis Intermediate: Acts as a precursor in the synthesis of more complex pharmaceutical molecules.

Quality Control

Our Oxaprozin is manufactured under strict quality management systems to ensure it meets the rigorous standards required for pharmaceutical applications. Each batch is tested against comprehensive specifications, including identity, purity, and impurity profiles, using validated analytical methods such as HPLC and IR spectroscopy. A Certificate of Analysis (COA) detailing all test results is provided with every shipment to guarantee traceability and compliance.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed to minimize exposure to atmospheric moisture. Keep away from incompatible materials.
