Quality Control

Our 5,6-Dibromohexahydro-4,7-Methanoisobenzofuran-1,3-Dione is produced under strict quality management protocols. Each batch undergoes rigorous analytical testing to ensure high purity and consistent performance. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are provided with every shipment and are available upon request.

Storage

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