Quality Control

Our 2-Methylpent-2-Ene-5-Boronic Acid Pinacol Ester is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC, NMR, and GC analysis, to ensure high chemical purity and identity confirmation. Certificates of Analysis (COA) with detailed specifications are provided for every shipment to guarantee reproducibility and reliability for your critical research and development processes.

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). Due to its hygroscopic nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent moisture absorption and decomposition.
