Quality Control

Every batch of [1,1-Biphenyl]-2,2,3,6-Tetrol (9Ci) is produced and tested under a strict quality management system. We ensure compliance with relevant industry standards, and a comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with each shipment. Our standard grade typically meets a purity specification of ≥97% (HPLC), with custom purity grades available upon request.

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 sensitivity to oxidation, it is recommended to store the product under an inert atmosphere (e.g., nitrogen or argon) for long-term preservation. Keep away from strong oxidizing agents.
