Quality Control

Our 3-(Methoxymethyl)Phenylboronic Acid, Pinacol Ester is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing, including HPLC, NMR, and GC analysis, to ensure high chemical purity and consistency. Certificates of Analysis (COA) with detailed specifications are provided for each lot, supporting compliance in regulated research and production environments.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed to exclude moisture. Keep away from incompatible materials such as strong oxidizing agents.
