Quality Control

Our trans-4-Ethoxy-4'-(4-Propylcyclohexyl)-1,1'-Biphenyl is produced under strict quality management systems to ensure batch-to-batch consistency for critical display applications. We employ advanced analytical techniques, including HPLC and GC, to verify high chemical purity and precise isomeric composition. A comprehensive Certificate of Analysis (COA) detailing identity, assay, and impurity profiles is provided with every shipment.

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 light-sensitive nature and propensity for oxidation, it is recommended to store under an inert atmosphere (e.g., nitrogen or argon) for long-term preservation of quality.
