Quality Control

Our 2-Methylsulfanylphenylboronic Acid, Pinacol Ester is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing, including HPLC, NMR, and GC-MS, to ensure high chemical purity and identity. Certificates of Analysis (COA) documenting all specifications are available upon request to support your quality assurance and regulatory needs.

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 minimize exposure to atmospheric moisture. For long-term storage, consider using an inert atmosphere.
