Quality Control

Our 3-Pyridinecarboxaldehyde, 1,2,5,6-Tetrahydro-4-Hydroxy-2-Oxo- (9Ci) is produced under strict quality management protocols. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation by spectroscopic methods, to ensure it meets the high standards required for research and development applications. Certificates of Analysis (COA) detailing batch-specific results are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic (moisture-sensitive) nature and propensity to be easily oxidized, it is recommended to store the material under an inert atmosphere (e.g., nitrogen or argon) at a controlled room temperature (15-25°C). Minimize exposure to air and moisture during handling to maintain product integrity.
