Quality Control

Our (E)-2-(3,4-Dimethoxystyryl)-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-MS, to ensure high purity and consistent performance for critical coupling reactions. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are available upon request to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place. Due to its hygroscopic (moisture-sensitive) nature, it is recommended to handle the material under an inert atmosphere (e.g., nitrogen or argon) for long-term storage and to minimize exposure to ambient humidity during use. Ideal storage temperature is 2-8°C for prolonged stability.
