Quality Control

Our Bicyclo[4.1.0]Hept-3-Ene-7-Carbonyl Chloride (9Ci) is produced and handled under strict quality management protocols to ensure batch-to-batch consistency and reliability. Each lot undergoes comprehensive analytical testing, including purity assay and impurity profiling. A Certificate of Analysis (COA) detailing all specifications is provided with every shipment to support your quality assurance and regulatory needs.

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 and moisture-sensitive nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent decomposition. Keep away from strong bases, oxidizing agents, and sources of ignition.
