Abstract
The quenching compounds of the invention are nitrogen-substituted xanthenes that are substituted by one or more aromatic or heteroaromatic quenching moieties. The quenching compounds of the invention exhibit little or no observable fluorescence and efficiently quench a broad spectrum of luminescent compounds. The chemically reactive quenching compounds possess utility for labeling a wide variety of substances, including biomolecules. These labeled substances are highly useful for a variety of energy-transfer assays and applications.
