Quality Control

Our 2-Hydroxy-4-Pyridinecarboxaldehyde is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation via FT-IR and NMR spectroscopy, to ensure it meets the high standards required for research and synthesis. A Certificate of Analysis (COA) detailing all specifications is provided with 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 tightly sealed after use to prevent degradation from atmospheric moisture.
