Quality Control

Our production of this advanced cyanine dye adheres to strict quality protocols to ensure batch-to-batch consistency and performance reliability. Each lot is characterized using advanced analytical techniques including HPLC, NMR, and Mass Spectrometry to confirm identity, purity, and the absence of critical impurities. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with every shipment to support your R&D and quality assurance processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). This compound is hygroscopic (moisture-sensitive); therefore, the container must be kept tightly sealed in a dry environment to prevent degradation. For long-term storage, consider using desiccants.
