Quality Control

Our 4,4,5,5-Tetramethyl-2-(4-Vinylphenyl)-1,3,2-Dioxaborolane is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing, including HPLC, NMR, and GC analysis, to ensure high purity and consistency. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is 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 place at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation.
