Quality Control

Our (1R,2R)-2-[(Diphenylmethylene)Amino]-Cyclopentanol is manufactured under strict quality management systems. Each batch is subjected to comprehensive analytical testing, including chiral purity verification by HPLC, to ensure it meets the high standards required for advanced synthetic applications. Certificates of Analysis (COA) detailing identity, purity, and enantiomeric excess are provided with every shipment.

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 should be kept in a desiccated environment and allowed to reach ambient temperature before opening to minimize moisture uptake.
