Quality Control

Our Dansyl-Dl-Norleucine Cyclohexylammonium Salt is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation, to ensure it meets the high standards required for research and analytical applications. A detailed Certificate of Analysis (COA) is provided with every shipment, documenting key parameters such as assay, related substances, and residual solvents.

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, which can affect stability and performance. For long-term storage, consider storing under an inert atmosphere.
