DusQ® 21 is a fluorescence quencher. DusQ 21 possesses broad absorption in far red and NIR range, and can quench fluorescence of dyes that emit in this region. This is a carboxylic acid derivative.

DusQ 21 has intense absorption maximum at 656 nm, making it useful as an acceptor in fluorescence resonance energy transfer (FRET) applications. It is a common quencher for Cyanine5, Cyanine5.5, AF 647, or other spectrally similar fluorescent dyes.
