Quality Control

Our (2-Ethoxycarbonylmethylphenyl)Boronic Acid, Pinacol Ester is manufactured under strict quality management systems. Every batch undergoes comprehensive analytical testing, including NMR (¹H, ¹³C, ¹¹B), HPLC, and GC, to ensure identity, purity, and consistency. A Certificate of Analysis (COA) detailing all specifications is provided with each shipment, supporting your quality assurance and regulatory compliance needs.

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); keep the container tightly sealed under an inert atmosphere (e.g., nitrogen or argon) for long-term storage to maintain optimal purity and stability.
