Product Description	Hydrazide derivative of Cyanine 7, 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.
Product form	Green powder.
