Quality Control

Every batch of 2,3,5,6-Tetrachloroisonicotinoyl Chloride is produced and tested under a strict quality management system. We employ advanced analytical techniques including HPLC, GC, and NMR to ensure identity, purity, and consistency. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with each shipment, and we support customer audits to ensure compliance with your internal quality standards.

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 nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent moisture ingress and decomposition.
