Quality Control

Our production of Triphenyl[3-(4,4,5,5-Tetramethyl-1,3,2-Dioxaborolan-2-Yl)Phenyl]Silane adheres to stringent quality management protocols. Each batch undergoes comprehensive analytical characterization, including NMR (1H, 13C, 11B), HPLC, and GC analysis, to ensure identity, purity, and consistency. Certificates of Analysis (COA) detailing all specifications are provided with every shipment. We support cGMP compliance for advanced intermediates and can tailor quality documentation to meet specific regulatory or customer requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place. Due to its hygroscopic nature, it is recommended to handle and store the material under an inert atmosphere (e.g., nitrogen or argon) to maintain optimal purity and stability. Recommended long-term storage temperature is 2-8°C.
