Quality Control

Our cis-Stilbeneboronic Acid Pinacol Ester is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC, NMR, and GC-MS, to ensure high chemical purity and consistent performance in sensitive cross-coupling applications. Certificates of Analysis (COA) with detailed specifications are provided with every shipment to guarantee traceability and compliance with your research and production requirements.

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). This material is hygroscopic (moisture-sensitive) and should be handled under an inert atmosphere (e.g., nitrogen or argon) for long-term storage and to maintain optimal reactivity.
