Quality Control

Our Dansyl-L-Methionine, Cyclohexylammonium Salt is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity, spectroscopic identification, and specific tests for residual solvents and moisture, to ensure it meets the stringent requirements of research and analytical applications. A detailed Certificate of Analysis (COA) is provided with every shipment to guarantee traceability, consistency, and compliance with your 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 (moisture-sensitive) nature, the container must be kept tightly sealed in a dry environment to prevent degradation. For long-term storage, consider desiccated conditions.
