Quality Control

Our 2-Chloro-6-Hydroxyisonicotinic Acid is manufactured under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation, to ensure it meets the stringent requirements of our global clientele. A detailed Certificate of Analysis (COA) is provided with every shipment, documenting key parameters such as assay, related substances, and residual solvents.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed after each use to prevent moisture absorption, which can affect product stability and performance.
