Quality Control

Our 3,9-Dihydroxyoctahydrodibenzo(A,G)Biphenylene is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity and spectroscopic identification (IR, NMR), to ensure it meets exacting research and development standards. A detailed Certificate of Analysis (COA) is provided with every shipment, documenting critical quality attributes. We support compliance with REACH and other relevant global regulatory frameworks.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed to prevent moisture absorption, which may affect stability and performance. Keep away from incompatible materials.
