Quality Control

Our production of 1,4-Bis(Dimethyl(2-(5-Norbornen-2-Yl)Ethyl)Silyl)Benzene adheres to stringent quality protocols to ensure batch-to-batch consistency and high purity. Each lot is analyzed using advanced techniques including HPLC, GC, and NMR to verify identity and purity. A comprehensive Certificate of Analysis (COA) detailing all specifications 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 a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent moisture absorption and degradation.
