Quality Control

Our Isopropenylboronic Acid Pinacol Ester is manufactured under strict quality management protocols. Each batch undergoes rigorous analytical testing, including NMR (¹H, ¹¹B, ¹³C), GC/HPLC for purity, and identity confirmation by IR spectroscopy, to ensure compliance with high-purity reagent standards. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with every shipment to guarantee traceability and batch-to-batch consistency for your critical applications.

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 compound is hygroscopic (moisture-sensitive) and should be handled under an inert atmosphere (e.g., nitrogen or argon) for prolonged use or when opening the primary container to prevent degradation.
