Quality Control

Our 3-Hydroxypyridine-4-Carboxaldehyde is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation by FT-IR and NMR spectroscopy, to ensure it meets the high standards required for research and industrial synthesis. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with every shipment to guarantee traceability and consistency.

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 sensitivity to oxidation, it is recommended to handle under an inert atmosphere for long-term storage or after opening. Keep away from heat, sparks, and open flame.
