Quality Control

Our 6-Oxo-4-Phenoxy-1-Phenyl-1,6-Dihydro-3-Pyridazinecarbonitrile is manufactured under strict quality management systems. Every batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation, to ensure it meets the stringent requirements for pharmaceutical intermediate applications. A detailed Certificate of Analysis (COA) is provided with each shipment, documenting batch-specific results.

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 after opening to prevent degradation from atmospheric moisture.
