Quality Control

Every batch of our 4,4,5,5-Tetramethyl-2-(4-(Triphenylen-2-Yl)Phenyl)-1,3,2-Dioxaborolane is manufactured under strict quality management systems. We guarantee high purity and lot-to-lot consistency through rigorous analytical testing, including HPLC, NMR, and GC-MS. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with each shipment to ensure it meets your specific research or production requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place 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) after opening to prevent moisture absorption and decomposition. Keep away from incompatible materials such as strong oxidizing agents.
