Quality Control

Our production of this cyanine dye adheres to strict quality management protocols to ensure batch-to-batch consistency and high performance. Each lot is characterized using advanced analytical techniques including HPLC, NMR, and UV-Vis spectroscopy to confirm identity, purity, and critical photophysical specifications. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with every shipment to support your quality assurance and R&D processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Keep away from heat, sparks, and open flame. Due to its perchlorate content and light-sensitive nature, appropriate safety measures for oxidizers should be observed.
