Quality Control

Our production of Tricyclo[2.2.1.02,6]Heptane, 3-Isocyanato-5-(Isocyanatomethyl)- (9Ci) adheres to stringent quality protocols to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analysis, including assay by titration or HPLC, determination of isocyanate (NCO) content, and control of key impurities and hydrolyzable chlorine. A Certificate of Analysis (COA) detailing all test results is provided with every shipment to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at temperatures between 15-25°C (59-77°F). Due to its hygroscopic (moisture-sensitive) nature, containers must be kept tightly sealed under a dry inert atmosphere (e.g., nitrogen or argon) after opening to prevent reaction with atmospheric moisture. Isolate from sources of heat, ignition, and incompatible materials such as alcohols, amines, and strong bases.
