Cy7 hydrazide

Hydrazide derivative of Cyanine7, a NIR fluorescent dye, an analog of Cy7¨.

This variety of heptamethine fluorophore contains a six-membered ring rigidizing the polymethine chain which allows to increase quantum yield by 20% compared to parent structure. Hydrazide reacts quickly and smoothly with aldehydes and ketones yielding stable hydrazone products. This reaction is also good for the labeling of glycoproteins after periodate oxidation.
