Quality Control

Our 3-Pyridinecarbonylchloride,2-Chloro-,1-Oxide(9Ci) is produced under stringent quality management protocols to ensure batch-to-batch consistency and high purity suitable for research and development applications. Each lot undergoes comprehensive analytical characterization, including HPLC for purity and NMR/IR for structural confirmation. Certificates of Analysis (COA) detailing all specifications are provided with every shipment to support your quality assurance and regulatory documentation needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place. Due to its hygroscopic nature, the container should be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent moisture absorption and degradation. Recommended long-term storage temperature is 2-8°C.
