Quality Control

Our 4,4,5,5-Tetramethyl-2-(4-Methylcyclohex-1-Enyl)-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 purity and consistency suitable for demanding synthetic applications. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with each shipment to guarantee reliable performance in your critical coupling reactions.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at 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 decomposition and maintain product integrity.
