Quality Control

Our production of 1,2-Bis(3-(4,4,5,5-Tetramethyl-1,3,2-Dioxaborolan-2-Yl)Phenoxy)Ethane adheres to stringent quality management protocols. Every batch undergoes comprehensive analytical testing, including NMR, HPLC, and GC analysis, to ensure identity, purity, and consistency. Certificates of Analysis (COA) documenting all critical parameters are provided with each 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) after opening to prevent moisture absorption and decomposition.
