Quality Control

Our Pirsidomine is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. The product undergoes rigorous analytical testing, including HPLC, NMR, and mass spectrometry, to confirm identity and potency. A comprehensive Certificate of Analysis (COA) detailing purity, impurities, and physical characteristics is provided with each shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed in a dry environment to prevent moisture absorption. For long-term storage, consider using desiccants.
