Quality Control

Our 9-Hydroxy-4-Oxo-4H-Pyrido[1,2-A]Pyrimidine-3-Carboxylic Acid is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure it meets the high standards required for pharmaceutical R&D. Certificates of Analysis (COA) with detailed specifications are provided for every shipment to guarantee traceability and batch-to-batch consistency.

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. For long-term storage, consider using desiccants.
