Quality Control

Our 3-Cyano-4-Methoxyphenylboronic Acid Pinacol Ester is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC, NMR, and IR spectroscopy, to ensure high chemical purity and identity. Certificates of Analysis (COA) with detailed specifications are provided for every shipment, supporting your R&D and regulatory documentation 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) and should be handled under inert atmosphere (e.g., nitrogen or argon) for long-term storage or after opening to maintain stability and purity.
