Quality Control

Our 4-Amino-5-Nitro-2-Pyridinol is produced under a strict quality management system. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure it meets exacting standards for research and industrial use. Certificates of Analysis (COA) with complete batch data are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Due to its light-sensitive nature and propensity to be easily oxidized, prolonged exposure to light and air should be avoided. For long-term storage, consider an inert atmosphere.
