Quality Control

Our o-Phenylene Borate 97+% is manufactured under strict quality management protocols. Each batch undergoes rigorous analytical testing to ensure it meets the declared purity and specification. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is available upon request 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 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) to prevent degradation from moisture and oxidation.
