Quality Control

Our Boronic Acid, B-(5-Ethyl-2-Hydroxyphenyl)- is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC, NMR, and elemental analysis, to ensure high purity and consistency. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with every shipment 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 a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation from atmospheric moisture. Keep away from incompatible materials.
