Quality Control

Our production of this cyanine dye adheres to stringent quality protocols to ensure batch-to-batch consistency and performance reliability. Every lot is characterized using advanced analytical techniques including HPLC, UV-Vis-NIR spectroscopy, and NMR to confirm identity, purity, and spectral properties. A comprehensive Certificate of Analysis (COA) detailing all test results 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). This material is hygroscopic (moisture-sensitive) and light-sensitive; prolonged exposure to air, moisture, or light may degrade product performance. Keep the container tightly sealed in a desiccated environment when not in use.
