Quality Control

Our 1,1'-Biphenyl, 4,4'-Bis(4-Ethylcyclohexyl)- is produced under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure it meets precise customer specifications and high-purity standards. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with every shipment and is available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C/59-77°F). Due to its sensitivity to oxidation, it is recommended to store under an inert atmosphere (e.g., nitrogen or argon) for long-term preservation. Keep away from heat, sparks, and open flame.
