Quality Control

Our 3-Fluoro-5-(Methylthio)Phenylboronic Acid is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing, including HPLC for purity and NMR for structural confirmation, to ensure it meets the high standards required for research and commercial synthesis. Certificates of Analysis (COA) with full traceability are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled 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) to prevent moisture absorption and decomposition.
