Quality Control

Our production of this specialty 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 and purity. A comprehensive Certificate of Analysis (COA) detailing purity, absorbance/emission profiles, and impurity limits 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). The container should be kept in a well-ventilated area, separate from incompatible materials, due to the perchlorate moiety. Handle and store in accordance with all local and international regulations for oxidizing substances.
