Quality Control

Our 5-(Methoxycarbonyl)Naphthalene-1-Boronic Acid Pinacol Ester is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing including HPLC, NMR, and GC-MS to ensure identity, purity, and consistency. Certificates of Analysis (COA) with detailed specifications are provided to guarantee the material meets the high standards required for research and development applications.

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 and easily oxidized nature, it is recommended to store the material under an inert atmosphere (e.g., nitrogen or argon) for long-term preservation and to minimize degradation.
