Quality Control

Our 1H-Pyrimido[4,5-C][1,2,6]Oxadiazine (9Ci) is produced under strict quality management protocols to ensure batch-to-batch consistency and high purity suitable for research and development applications. Each lot is characterized using advanced analytical techniques including NMR, HPLC, and mass spectrometry. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place. Due to its hygroscopic nature, it is recommended to handle and store the material under an inert atmosphere (e.g., nitrogen or argon) for long-term preservation, especially after opening the original container. Recommended storage temperature is 2-8°C for extended stability.
