Quality Control

Our trans-2-(3,4-Difluorophenyl)-5-(trans-4-n-Butylcyclohexyl)-1,3-Dioxane is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing, including chiral purity verification by HPLC, to ensure it meets the exacting standards required for advanced material and pharmaceutical synthesis. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with each shipment to guarantee traceability and consistency for your critical processes.

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 hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation from atmospheric moisture. For long-term storage, consider the use of desiccants.
