Quality Control

Our Bicyclo[4.2.0]Octa-1,3,5,7-Tetraene-7-Carboxylic Acid (9Ci) is produced under strict quality management protocols. Each batch undergoes rigorous analytical testing, including HPLC for purity and NMR for structural confirmation, to ensure it meets exacting R&D and process chemistry standards. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with every shipment to guarantee traceability and consistency.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at controlled room temperature (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.
