Quality Control

Our 2-Chloro-3,4-Diiodopyridine is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity and NMR/IR for structural confirmation, to ensure it meets the high standards required for research and development. Certificates of Analysis (COA) documenting identity, purity, and impurity profiles are available for every shipment.

Storage

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