Description

Metamizole Magnesium is a non-narcotic analgesic and antipyretic pharmaceutical active ingredient. This compound is valued for its potent pain-relieving and fever-reducing properties, making it a critical intermediate in the production of effective analgesic formulations. It is primarily utilized by pharmaceutical manufacturers and research institutions in the development of finished dosage forms for the management of moderate to severe pain and high fever.

Application

• Primary active pharmaceutical ingredient (API) in analgesic and antipyretic injectable solutions.
• Key intermediate in the synthesis of solid oral dosage forms such as tablets and capsules.
• Used in pharmaceutical research and development for new analgesic combination therapies.
• Employed in the manufacturing of prescription medications for post-operative pain management.
• Applicable in veterinary pharmaceuticals for pain relief in animals.

Quality Control

Our Metamizole Magnesium is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing to ensure it meets high-purity standards suitable for pharmaceutical use. Certificates of Analysis (COA) documenting identity, purity, and impurity profiles are available upon request to support your regulatory and quality assurance needs.

Storage

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