Quality Control

Our 4-Propylphenyl-4'-trans-Ethylcyclohexylbenzoate is manufactured under strict quality management systems. Every batch undergoes comprehensive analytical testing, including HPLC, GC, and NMR, to ensure high chemical purity and isomeric consistency critical for performance in sensitive applications like liquid crystals. A detailed Certificate of Analysis (COA) is provided with each shipment, confirming compliance with agreed specifications.

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). This compound is hygroscopic (moisture-sensitive); therefore, the container must be kept tightly sealed to exclude moisture. Keep away from heat sources and incompatible materials.
