Quality Control

Our 1-[2-(3,4-Dihydroisoquinolin-2(1H)-Yl)-2-Oxoethyl]-5-Methyl-1H-Indole-2,3-Dione is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure it meets the high standards required for pharmaceutical research. Certificates of Analysis (COA) with detailed chromatographic data are provided for every shipment to guarantee traceability and consistency.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container should be kept in a desiccated environment to prevent moisture absorption, which may affect stability and handling properties.
