Quality Control

Our (1R,2R)-rel-1-Methyl-2-phenylcyclohexane-1,2-diol is produced under a strict quality management system. Each batch undergoes comprehensive analytical testing, including chiral purity assessment by HPLC, to ensure identity, strength, and composition. Certificates of Analysis (COA) detailing purity, enantiomeric excess, and impurity profiles are provided and available upon request to support your quality and regulatory requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place. Due to its hygroscopic nature, the container should be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) for long-term storage to prevent moisture absorption. Recommended storage temperature is 2-8°C for extended stability.
