Quality Control

Our β-(7-Chlorobenzo[B]Thien-2-Yl)Boronic 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 batch-to-batch consistency suitable for research and scale-up. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with each shipment.

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). This material is hygroscopic (moisture-sensitive) and should be handled under an inert atmosphere (e.g., nitrogen or argon) for long-term storage and to maintain stability.
