Quality Control

Our production of this high-value cyanine dye adheres to stringent quality protocols. Every batch undergoes comprehensive analysis, including HPLC for purity verification, spectrophotometric analysis for absorption/emission profiles, and elemental analysis. We provide detailed Certificates of Analysis (COA) with each shipment, ensuring traceability and compliance with your research or manufacturing specifications. Our quality system is designed to support applications requiring high batch-to-batch consistency and reliable performance.

Storage

Preserve in a tightly closed container, protected from light. Due to its strictly light-sensitive and hygroscopic nature, this material must be stored in a cool, dry place (recommended 2-8°C or as specified) under an inert atmosphere for long-term stability. The original container should be kept sealed in a desiccator to minimize moisture uptake and exposure to air.
