Quality Control

Our production of this cyanine dye adheres to stringent Good Manufacturing Practice (GMP) guidelines where applicable. Every batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation via spectroscopic methods, to ensure it meets the high standards required for sensitive research and diagnostic applications. A detailed Certificate of Analysis (COA) is provided with each shipment, and custom specifications can be developed to meet specific project requirements.

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); ensure the container is sealed tightly after each use to prevent degradation from atmospheric moisture. For long-term storage, consider desiccants or an inert atmosphere.
