Quality Control

Our Cy7 Acid(Triso3) is produced under stringent quality management protocols. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation via spectroscopic methods, to ensure it meets the high standards required for research and development. A comprehensive Certificate of Analysis (COA) detailing purity, absorbance/fluorescence profiles, and impurity levels is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at 2-8°C or as indicated on the label or COA. Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed under desiccant or inert atmosphere after opening to prevent degradation. Long-term storage is recommended at -20°C.
