Quality Control

Our 3-(Anilinomethylene)-1,6,7,11B-Tetrahydro-2H-Pyrido[2,1-A]Isoquinoline-2,4(3H)-Dione is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing, including HPLC, NMR, and MS, to ensure high purity and batch-to-batch consistency. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with each shipment. We support development under cGMP guidelines for pharmaceutical applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (typically 15-25°C). This compound is light-sensitive (store away from light) and may be hygroscopic (moisture-sensitive); therefore, containers should be kept sealed under an inert atmosphere when not in use to prevent degradation and moisture uptake.
