Quality Control

Our 2-[3-(2-Methoxyethoxy)Phenyl]-4,4,5,5-Tetramethyl-1,3,2-Dioxaborolane is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC, NMR, and GC analysis, to ensure high purity and consistency suitable for demanding synthetic applications. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are available upon request.

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) to prevent moisture absorption and decomposition.
