Quality Control

Our 3,5-Dichloro-4-Hydroxypyridine-2-Carboxylic Acid is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing, including HPLC, NMR, and IR spectroscopy, to ensure high purity and consistent identity. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with each shipment to support your quality assurance protocols.

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 nature, the container must be kept tightly sealed after opening to minimize exposure to atmospheric moisture. Keep away from incompatible materials.
