Stability Hygroscopic
Applications Quercitrin is known as an bio flavonoid antioxidant and was investigated extensively in its antioxidant potential in streptrozotocin (STZ)-induced diabetic rats. Quercitrin is also a constituent of the dye quercitron. Quercitrin can be found in Tartary buckwheat and in oaks species such as white oak or European red oak.

Applications CY5 Triethylamine salt is the salt form of CY5(C951310) which is a photoswitchable cyanine dye. The photoswitching mechanism was investigated using thiol agents and it was concluded that photoconversion into the dark state is pH and thiol dependent and the dark state product is a cyanine-thiol adduct.
