Quality Control

Our Bicyclo[2.2.1]Heptane-2-Carbonyl Chloride, 4,7,7-Trimethyl-3-Oxo-, (1R,2S,4R)- (9Ci) is produced under strict quality management systems. Each batch undergoes rigorous analytical testing, including chiral purity assessment by HPLC, to ensure it meets the high standards required for advanced synthetic applications. Certificates of Analysis (COA) detailing purity, enantiomeric excess, and impurity profiles are provided with every shipment to guarantee traceability and consistency for our global B2B clients.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area. Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent decomposition. Recommended long-term storage temperature is 2-8°C. Keep away from strong acids and organic solvents.
