Quality Control

Every batch of n-Bromo-4,5-Dichloro-6-Pyridazone is manufactured and tested under strict quality management protocols. We ensure consistent high purity and identity through comprehensive analytical methods including HPLC, NMR, and mass spectrometry. A Certificate of Analysis (COA) detailing purity, impurities, and full characterization data is provided with each shipment to guarantee it meets your specific research or production requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its hygroscopic and easily oxidized nature, it is recommended to handle under an inert atmosphere (e.g., nitrogen or argon) for long-term storage and to minimize exposure to moisture.
