Quality Control

Our 2-(2,4-Dimethylphenyl)-4,4,5,5-Tetramethyl-1,3,2-Dioxaborolane is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing, including NMR, HPLC, and GC analysis, to ensure high chemical purity and lot-to-lot consistency suitable for sensitive cross-coupling applications. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with each shipment.

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 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.
