Quality Control

Every batch of our 3,6-Diamino-9-[2-Carboxy-4-[(2,3,5,6-Tetrafluorophenoxy)Carbonyl]Phenyl]-4,5-Disulfoxanthylium Bis(Triethylammmonium) Salt undergoes rigorous analytical testing to ensure it meets the stringent purity and performance standards required for sensitive life science applications. Our quality assurance protocol includes advanced chromatographic and spectroscopic methods to verify identity, potency, and the absence of critical impurities. A comprehensive Certificate of Analysis (COA) documenting purity (typically >95% by HPLC), spectral data, and other key parameters is provided with each shipment to support your quality and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store at 2-8°C (refrigerated) or as indicated on the label or COA. This product is hygroscopic (moisture-sensitive) and light-sensitive. Allow the sealed container to equilibrate to room temperature before opening to prevent condensation and moisture uptake. For long-term storage, consider desiccant or under an inert atmosphere.
