Quality Control

Our production of Bicyclo[2.2.1]Hept-2-Ene-2-Carbonyl Chloride, 1,7,7-Trimethyl- (9Ci) adheres to stringent quality management protocols to ensure batch-to-batch consistency and high purity for research and development applications. All products undergo rigorous analytical testing, including chromatography (HPLC, GC) and spectroscopic methods (NMR, IR). A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with every shipment to support your quality assurance and regulatory documentation 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). This material is hygroscopic (moisture-sensitive) and reacts with strong acids and organic solvents; ensure the container is kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) for long-term storage to prevent hydrolysis and maintain stability.
