Quality Control

Our production of this cyanine dye adheres to stringent quality protocols to ensure batch-to-batch consistency and high performance in sensitive applications. Quality is verified through advanced analytical techniques including HPLC for purity and spectrophotometry for optical specification confirmation. A comprehensive Certificate of Analysis (COA) detailing identity, purity, absorbance/fluorescence maxima, and other critical parameters 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 product is hygroscopic (moisture-sensitive) and light-sensitive; therefore, containers must be kept sealed in a desiccated environment and handled under low-light conditions to prevent degradation. For long-term storage, consider inert atmosphere packaging.
