Cyanine 5.5 is a fluorophore with the emission in the far red range of the spectrum. This dye is useful for multiplex qPCR. Commercial six-channel qPCR instruments often have a channel for Cyanine 5.5. This phosphoramidite can be used for the synthesis of 5-labeled oligonucleotides by direct labeling in oligonucleotide synthesis. The structure of a phosphoramidite functional group that is attached to a secondary carbon atom provides extra stability against Arbuzov rearrangement. This helps maintaining coupling performance over a longer storage time in oligonucleotide synthesizer, compared to phosphoramidites derived of primary alcohols.
