Quality Control

Our Bicyclo[8.1.0]Undecane-11-Carbonyl Chloride (9Ci) is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including chromatography (HPLC/GC) and spectroscopic methods (NMR, IR), to ensure identity, purity, and consistency. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with every shipment to support your quality assurance protocols.

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 compound is hygroscopic (moisture-sensitive) and should be handled under an inert atmosphere (e.g., nitrogen or argon) to prevent decomposition. Keep away from strong acids, bases, and oxidizing agents.
