Quality Control

Our 4-Pyridinecarbonyl Chloride, 1,2-Dihydro-1-Methyl-2-Oxo- (9Ci) is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including HPLC, NMR, and IR spectroscopy, to ensure high purity and consistent chemical identity. Certificates of Analysis (COA) with detailed specifications are provided for every shipment, supporting your R&D and quality assurance requirements.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic and highly volatile nature, store under an inert atmosphere (e.g., nitrogen or argon) in a cool, dry, and well-ventilated place. Recommended storage temperature is 2-8°C for long-term stability. Keep away from strong acids and organic solvents.
