Quality Control

Our [4-(4,4,5,5-Tetramethyl-[1,3,2]Dioxaborolan-2-Yl)-Thiophen-2-Yl]-Methanol is produced under strict quality management protocols. Each batch undergoes rigorous analytical testing, including HPLC, NMR, and GC-MS, to ensure high chemical purity and identity confirmation. Certificates of Analysis (COA) detailing all specifications are provided with every shipment to guarantee traceability and batch-to-batch consistency for your critical applications.

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.
