Methods and compound useful for detecting a source of hydrogen peroxide are disclosed wherein a signalling compound of the formula: is reacted with peroxide. Sig is a non-polymeric organic group, B is a boron atom, and each R is independently selected from hydrogen, alkyl and aryl groups and can be joined together as a straight or branched alkylene chain forming a ring or as an aromatic ring. A detectable product compound of the formula Sig-OH or Sig-Ois produced and detected by measuring color, absorbance, fluorescence, chemiluminescence, or bioluminescence. The signalling compound itself does not possess the detectable property or does so only to a very weak degree. The methods can be used as a detectable signal in assays for peroxide or peroxide-producing enzymes and in assays employing enzyme-labeled specific binding pairs.

Signalling compounds and methods for detecting hydrogen peroxide

Compounds useful for detecting a source of hydrogen peroxide are disclosed wherein a signalling compound of the formula:is reacted with peroxide. Sig is an aromatic or heteroaromatic ring group, B is a boron atom, and Rand Rare independently selected from hydrogen and lower alkyl groups and can be joined together as a straight or branched alkylene chain forming a five or six-membered ring. A detectable product compound of the formula Sig-OH Is produced and detected by measuring color, fluorescence, chemiluminescence, or bioluminescence. The signalling compound itself does not possess the detectable property or does so only to a very weak degree. The compounds can be used for detection in assays for peroxide or peroxide-producing enzymes and in assays employing enzyme-labeled specific binding pairs.
