Quality Control

Our 2-Benzyl-5-Chloro-4-Iodopyridazin-3(2H)-One is manufactured under strict quality management systems. Each batch undergoes rigorous 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 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 at a controlled room temperature (typically 15-25°C). This compound is light-sensitive (store away from light) and may be hygroscopic (moisture-sensitive); therefore, the container should be kept sealed under an inert atmosphere for long-term storage to maintain stability.
