Quality Control

Every batch of 4,4,5,5-Tetramethyl-2-(3-Triphenylen-2-Yl-Phenyl)-[1,3,2]Dioxaborolane is manufactured under strict quality management systems. We employ advanced analytical techniques including HPLC, GC, NMR, and mass spectrometry to ensure identity, purity, and consistency. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with each shipment to support your quality assurance and R&D documentation.

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 (moisture-sensitive) nature, the container must be kept tightly sealed under an inert atmosphere (argon or nitrogen) after opening to prevent degradation. Keep away from incompatible materials.
