Quality Control

Our production of this high-purity cyanine dye adheres to stringent ISO 9001 quality management protocols. Every batch is characterized using advanced analytical techniques including HPLC, NMR, and Mass Spectrometry to confirm identity, purity, and photochemical properties. A comprehensive Certificate of Analysis (COA) detailing assay, impurity profile, and spectral data is provided with each shipment to ensure traceability and support your R&D and manufacturing requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). The container should be kept in a desiccator or under an inert atmosphere if long-term storage is required to prevent potential degradation. Keep away from heat and incompatible materials.
