green powder

moderate solubility in water, good in polar organic solvents (DMF, DMSO, alcohols)

-20°C

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.
