Quality Control

Our 1(3H)-Isobenzofuranone,4,7-Dihydroxy-(9Ci) is produced under stringent quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation via spectroscopic methods (IR, NMR), to ensure it meets the high standards required for research and industrial synthesis. Certificates of Analysis (COA) detailing all specifications are provided with every shipment. We are committed to consistent quality and supply reliability for our global B2B partners.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (typically 15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation from atmospheric moisture. Keep away from incompatible materials.
