Quality Control

Our trans-1-Hepten-1-Ylboronic Acid Pinacol Ester is manufactured under strict quality control protocols to ensure batch-to-batch consistency and high purity, essential for sensitive cross-coupling applications. Each lot is analyzed via NMR, HPLC, and GC to confirm identity, purity, and the absence of critical impurities. Certificates of Analysis (COA) detailing all specifications are provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) at 2-8°C in a cool, dry place. This compound is hygroscopic (moisture-sensitive) and easily oxidized; prolonged exposure to air, moisture, or elevated temperatures should be avoided to maintain stability and purity.
