Quality Control

Every batch of Bicyclo[2.2.1]Hepta-2,5-Diene-2-Carbonyl Chloride, 3-Methyl- (9Ci) is manufactured and tested under strict quality management protocols. We ensure high purity and lot-to-lot consistency through comprehensive analytical techniques including GC, HPLC, and NMR. A detailed Certificate of Analysis (COA) specifying identity, purity, and impurity profiles is provided with each 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 acids and incompatible materials.
