Quality Control

Our (1R,2R)-(-)-1,2-Dicyclohexyl-1,2-Ethanediol is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including chiral purity (enantiomeric excess) and chemical purity assays, to ensure it meets the high standards required for advanced synthetic applications. Certificates of Analysis (COA) with detailed chromatographic data are provided to guarantee batch-to-batch consistency and traceability.

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 minimize exposure to atmospheric humidity. For long-term storage, consider using desiccants or an inert atmosphere.
