Quality Control

Our Propyphenazone-Metamizol is manufactured under strict quality systems to ensure it meets the high-purity standards required for pharmaceutical applications. Each batch is tested against rigorous in-house specifications, which may include identity, assay, and impurity profile analysis via techniques such as HPLC and spectroscopy. Certificates of Analysis (COA) are 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 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.
