Quality Control

Our 2-Hydroxy-5-Pyridinecarboxylic Acid is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation, to ensure it meets the high standards required for synthesis and research. A detailed Certificate of Analysis (COA) is provided with every shipment, guaranteeing traceability and consistent quality. We support compliance with global regulatory frameworks.

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 (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation from atmospheric moisture.
