Quality Control

Our 2-Pyridinecarbonyl Chloride, 3-Chloro- (9Ci) is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation via FT-IR and NMR spectroscopy, to ensure it meets the high standards required for research and process chemistry. Certificates of Analysis (COA) with detailed batch-specific results are provided to guarantee traceability and consistency.

Storage

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