Cy7酰肼|Cyanine7 hydrazide|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 labe生 of glycoproteins after periodate oxidation.          Cy7酰肼|Cyanine7 hydrazide|Cy7 hydrazide   General properties： Appearance: green powder Mass spec M+ increment: 544.8 Molecular weight: 635.70 Molecular formula: C37H48Cl2N4O Solubility: moderate solubility in water, good in polar organic solvents (DMF, DMSO, alcohols) Storage conditions: Storage: 24 months after receival at -20°C in the dark.
