Quality Control

Our production of this high-value cyanine dye adheres to stringent quality protocols to ensure batch-to-batch consistency and performance reliability. Each lot is characterized using advanced analytical techniques including HPLC for purity assessment, UV-Vis and fluorescence spectroscopy for optical property verification, and NMR for structural confirmation. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and spectral data 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 hygroscopic (moisture-sensitive) and light-sensitive; ensure containers are sealed immediately after use to minimize exposure to atmospheric moisture and light, which can degrade the product.
