Quality Control

Our Ethyl 5-(4,4,5,5-Tetramethyl-1,3,2-Dioxaborolan-2-Yl)Furan-3-Carboxylate is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing, including HPLC, NMR, and GC-MS, to ensure high purity and consistent performance for sensitive cross-coupling applications. Certificates of Analysis (COA) with detailed specifications are provided for each shipment, ensuring full traceability and compliance with your research or production requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled 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.
