Quality Control

Our (4'-Pentyl[1,1'-Biphenyl]-4-Yl)-Boronic Acid is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and NMR for structural confirmation, to ensure it meets the high standards required for sensitive coupling reactions. Certificates of Analysis (COA) detailing purity, assay, and impurity profiles are available upon request.

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 (moisture-sensitive) nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) for long-term storage to maintain optimal purity and reactivity.
