Quality Control

Our (4S,4'S,5R,5'R)-2,2'-(Pentane-3,3-Diyl)Bis(4,5-Diphenyl-4,5-Dihydrooxazole) is produced under strict quality management systems. Each batch undergoes rigorous analytical testing, including chiral purity analysis by HPLC, to ensure high enantiomeric excess (ee) and chemical purity. Certificates of Analysis (COA) with full characterization data are provided to guarantee batch-to-batch consistency and compliance with your research or production specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed in a dry environment to prevent moisture absorption. For long-term storage, consider using desiccants or an inert atmosphere.
