Quality Control

Our 2,2'-Bipyridine boronic ester is manufactured under strict quality protocols to ensure batch-to-batch consistency and high purity. We employ advanced analytical techniques including HPLC, NMR (1H, 13C, 11B), and mass spectrometry for comprehensive characterization and purity verification. A detailed Certificate of Analysis (COA) is provided with each shipment, confirming specifications for identity, assay, and impurity profiles. Our quality system is designed to meet the stringent requirements of research and cGMP-grade manufacturing.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place. Due to its hygroscopic (moisture-sensitive) nature, it is recommended to store the product under an inert atmosphere (e.g., nitrogen or argon) for long-term preservation and to handle it in a dry environment to prevent hydrolysis of the boronic ester group. Recommended storage temperature is 2-8°C for optimal stability.
