Quality Control

Our 9-Hydroxy-4-Oxo-4H-Pyrido[1,2-A]Pyrimidine-3-Carboxylic Acid Ethyl Ester is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation via spectroscopic methods, to ensure it meets the high standards required for research and synthesis. Certificates of Analysis (COA) documenting all specifications are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at controlled room temperature (typically 15-25°C). Keep away from incompatible materials. Due to its light-sensitive nature, containers should be amber-colored or stored in light-resistant secondary packaging.
