Quality Control

Our production of this advanced cyanine dye adheres to strict quality management protocols to ensure batch-to-batch consistency and performance reliability. The material undergoes comprehensive analytical characterization, including HPLC for purity, NMR for structural confirmation, and UV-Vis-NIR spectroscopy to verify key optical properties. A detailed Certificate of Analysis (COA) documenting identity, purity, and relevant specifications is provided with each shipment to support your quality assurance and regulatory needs.

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 using an inert atmosphere.
