Quality Control

Every batch of 2,2',3-Trihydroxydiphenyl Ether is produced under a strict quality management system. Our products undergo rigorous analytical testing to ensure compliance with agreed specifications and high purity standards. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with each shipment. We support custom purity requirements and can tailor specifications for research, pilot, or commercial-scale applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its light-sensitive nature and propensity to be easily oxidized, it is recommended to store the material under an inert atmosphere (e.g., nitrogen or argon) for long-term preservation. Keep away from strong oxidizing agents.
