The invention concerns compounds based on benzoxazoles wherein selected substituents are each a reactive group A bound via a linker L and adapted to covalently bond a compound of the invention to a to-be-marked molecule K, wherein A is an amine, hydroxy or phosphoramidite function, a carboxylic acid, an alkyl or active ester derived therefrom; a carboxylic acid hydrazide; or a carboxylic acid amide where
K is a covalently bound component selected from the group haptenes−, proteins (antibodies), low molecular weight drug compounds, peptides, nucleotides, nucleosides, DNA oligomers, polymers, and t is from 1 to 10, and
L is a linker selected from a group featuring —(CH
