Quality Control

Our Ethyleneboronic Acid is produced under a strict quality management system. Every batch undergoes comprehensive analytical testing, including HPLC, NMR, and elemental analysis, to ensure high chemical purity and consistency. A Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with each 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 area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation.
