Quality Control

Our 1,2,3,4,5,6-Hexaphenylcyclohexasilane is produced under stringent conditions to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including NMR (¹H, ²⁹Si), HPLC, and elemental analysis, to verify identity and purity. A Certificate of Analysis (COA) detailing all test results is provided with every shipment, ensuring full traceability and compliance with your research or production specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed after opening to minimize exposure to atmospheric moisture. For long-term storage, consider using an inert atmosphere or desiccant.
