Quality Control

Every batch of 3-Pyridinecarbonyl Chloride, 6-Chloro-5-Formyl- (9Ci) is produced and tested under a strict quality management system. We employ advanced analytical techniques including HPLC, GC, NMR, and mass spectrometry to ensure identity, purity, and consistency meet the exacting standards required for research and process chemistry. A comprehensive Certificate of Analysis (COA) detailing all specification parameters is provided with each shipment and is available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature and reactivity as an acid chloride, 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 bases, oxidizing agents, and moisture.
