Quality Control

Our Dansyl-Dl-Phenylalanine Cyclohexylammonium Salt is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity, NMR and IR for structural confirmation, and loss on drying for moisture content. A Certificate of Analysis (COA) detailing all specifications and test results is provided with every shipment to ensure traceability and compliance with your research or quality standards.

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 to prevent moisture absorption. For long-term stability, consider storage under an inert atmosphere.
