Quality Control

Our Bicyclo[2.2.1]Hept-5-Ene-2-Carbonyl Chloride, 3-Ethenyl-, (Endo,Endo)- (9Ci) is produced under stringent quality management systems. Each batch undergoes rigorous analytical testing, including HPLC, GC, NMR, and IR spectroscopy, to ensure identity, purity, and consistency. Certificates of Analysis (COA) detailing all specifications are provided with every shipment. We are committed to meeting the exacting standards required for research and commercial-scale synthesis.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic (moisture-sensitive) nature and reactivity as a strong acid/organic solvent derivative, this material must be stored under an inert atmosphere (e.g., nitrogen or argon) in a cool, dry, and well-ventilated area. Recommended long-term storage temperature is between 2°C and 8°C. Allow the sealed container to reach ambient temperature before opening to prevent moisture condensation.
