Quality Control

Our Diazenecarbonitrile, 2-Pyrimidinyl-, 2-Oxide (9Ci) is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including HPLC for purity and NMR for structural confirmation, to ensure it meets the high standards required for research and development applications. A detailed Certificate of Analysis (COA) is provided with every shipment, documenting identity, purity, and impurity profiles.

Storage

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