Quality Control

Our 3-Pyridazinecarbonyl Chloride, 1,6-Dihydro-1-Methyl-6-Oxo- (6Ci,7Ci) is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including HPLC, NMR, and IR spectroscopy, to ensure identity, purity, and consistency. Certificates of Analysis (COA) detailing all specifications are provided to guarantee the material meets your research and development requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent decomposition. Keep away from strong acids and incompatible organic solvents.
