Quality Control

Our (4S)-6,8-Dimethyl-3,4-Dihydro-2H-1-Benzopyran-4-Amine is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including chiral purity (enantiomeric excess) and chemical purity determination by HPLC, to ensure compliance with customer specifications and research-grade standards. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed after opening to minimize exposure to atmospheric moisture. For long-term storage, consider using desiccants or an inert atmosphere.
