Description

Cinaproxen is a non-steroidal anti-inflammatory drug (NSAID) belonging to the arylpropionic acid class, known for its potent analgesic and antipyretic properties. This high-purity active pharmaceutical ingredient (API) is critical for ensuring the efficacy and safety of finished pharmaceutical formulations. It is primarily utilized by pharmaceutical manufacturers in the research, development, and production of prescription and over-the-counter medications for managing pain and inflammation.

Application

• Pharmaceutical API: Primary active ingredient in solid oral dosage forms such as tablets and capsules.
• Analgesic Formulations: Used in medications for the relief of mild to moderate pain, including headaches, dental pain, and musculoskeletal discomfort.
• Anti-inflammatory Therapeutics: Key component in drugs designed to reduce inflammation associated with conditions like arthritis and tendinitis.
• Antipyretic Medications: Incorporated into formulations aimed at reducing fever.
• Veterinary Pharmaceuticals: Applied in the development of anti-inflammatory and pain management treatments for animals.
• Reference Standard: Serves as a high-purity chemical standard in analytical laboratories for quality control and method development.
• Research & Development: Used in preclinical and clinical studies to investigate new therapeutic applications and delivery mechanisms.

Quality Control

Our Cinaproxen is manufactured under strict quality management systems to ensure it meets the rigorous standards required for pharmaceutical applications. Each batch is subjected to comprehensive analytical testing, including identification, assay, and impurity profiling via techniques like HPLC and IR spectroscopy. We provide full traceability and Certificates of Analysis (COA) are available for every shipment to guarantee compliance with your specifications and relevant pharmacopeial guidelines.

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 (moisture-sensitive) nature, the container must be kept tightly sealed after each use to prevent degradation from atmospheric moisture.
