Abstract:
A method of detecting an analyte using labeling groups comprising the step of labeling the analyte with compounds of the general formula I as labeling groups and utilizing a procedure for the detection of an analyte; whereinY is one of oxygen or Nâ€”R8; R1, R2, R3 and R8, each are independently a member of the group, selected from hydrogen, a phenyl group, a phenylalkyl group having 1â€”3 C atoms in the alkyl chain, a polyether group or a hydrocarbon group having up to 20 C atoms, and optionally containing one or more substituents, selected from at least one of halogens, amino, sulfo, carboxyl, aldehyde, alkoxy and alkoxycarbonyl groups, or one or more of the radicals R1, R2, R3 and R8 form a ring system with a suitable adjacent substituent; R4, R5, R6 and R7 are each independently, a member selected from the group of hydrogen, halogen, phenyl, a hydroxyl, amino, sulfo, a carboxyl group or a hydrocarbon derivative having up to 15 C atoms; wherein the hydrocarbon derivatives comprise at least one of an alkyl, alkenyl, alkynyl, cycloalkyl, aryl and heteroaryl radicals and optionally each, member contains at least one or more substituents, selected the group of halogens, amino, sulfo, carboxyl, aldehyde, alkoxy and alkoxycarbonyl groups, wherein one or more of the radicals R4, R6 and R7 can form a ring system with an adjacent substituent; and wherein Cyc is an organic radical which comprises a ring system selected from at least one of aromatic, heteroaromatic, quinoid and cycloaliphatic rings, which can optionally contain one or more substituents selected from at least one of halogens, amino, hydroxyl, sulfo, carbonyl, aldehyde, alkoxy and alkoxycarbonyl groups, and X represents optionally anion species present for charge equalization.
