Cyanine5 Boc-hydrazide|Cy5 Boc-hydrazide
 
Boc-protected Cyanine5 hydrazide reactive dye for the labeling of aldehydes and ketones.
Boc- (tert-butoxycarbonyl) protective group can be removed with trifluoroacetic acid, or other strong acid. Reactive hydrazide is formed, which can then couple with various carbonyl groups yielding Cyanine5-labeled molecules.
