Cyanine5 is one of the dyes that are used in qPCR. The corresponding filter set is found on many qPCR machines.

This reactive derivative is useful for the synthesis of qPCR probes having Cyanine5 at 5′-end, the most typical location of the fluorophore. This is a terminating, non-nucleoside reagent.

Amidite group in this reagent is bound to a secondary oxygen. This provides extra stability against Arbuzov rearrangement - a reaction that leads to amidite deterioration in solution in oligonucleotide synthesizer. This molecular design increases the stability of the reagent, maintaining efficient coupling over a longer time.
