Quality Control

Our 6-Cyanobenzo[B]Thiophen-2-Ylboronic Acid is manufactured under strict quality control protocols to ensure batch-to-batch consistency and high purity, typically ≥95% (HPLC). Each lot is accompanied by a comprehensive Certificate of Analysis (COA) detailing purity, identity confirmation via spectroscopic methods, and impurity profiles. We adhere to cGMP guidelines where applicable to support our clients in regulated research and development.

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 (moisture-sensitive) nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation.
