Quality Control

Our 4,5-Dimethoxy-2-Phenylpyridazin-3(2H)-One is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing, including HPLC for purity, NMR and IR for structural confirmation, and tests for residual solvents and heavy metals. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with each shipment to ensure traceability and compliance with your research or production requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area 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. Keep away from incompatible materials.
