Quality Control

Our production of this specialty cyanine dye adheres to strict batch-to-batch consistency protocols. Quality is verified through advanced analytical techniques including HPLC, NMR, and UV-Vis spectroscopy to ensure conformity to specified photochemical properties. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and performance characteristics is provided with each 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). Due to its hygroscopic nature, the container must be kept in a desiccated environment to prevent moisture absorption, which can affect performance. Keep away from incompatible materials.
