Quality Control

Our production of this cyanine dye adheres to stringent quality protocols to ensure batch-to-batch consistency and performance reliability for sensitive optical applications. Each lot is characterized using advanced analytical techniques including HPLC, NMR, and UV-Vis-NIR spectroscopy. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and spectral properties is provided with every shipment.

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 light-sensitive and easily oxidized; for long-term storage, it is recommended to keep the container under an inert atmosphere such as argon or nitrogen.
