Quality Control

Our 4-Cyano-3-Methylphenylboronic Acid is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing, including HPLC, NMR, and elemental analysis, to ensure high purity and consistency. Certificates of Analysis (COA) detailing batch-specific results are provided and available upon request, supporting compliance with research and cGMP guidelines for advanced intermediates.

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 to exclude moisture. For long-term storage, consider using desiccants or storing under an inert atmosphere.
