摘要:
A method for detecting hydrogen peroxide wherein a sample is contacted with a peroxidase or a peroxidatively-active substance and a redox indicator of the following ##STR1## in which A and D independently of one another represent phenyl, pyridyl or imidazolyl,G represents O, CH.sub.2 or S,m represents the number zero or one, andX represents O, ##STR2## or --NR.sup.1 --NR.sup.2 -- R.sup.1 and R.sup.2, independently of one another, denote hydrogen, alkyl, cycloalkyl, aryl or aralkyl, or --NR.sup.1 R.sup.2 together represent a pyrrolidine, pyrazoline, piperidine, piperazine or morpholine radical andT denotes hydrogen, hydroxyl, alkyl, aryl, alkoxy, phenoxy, SO.sub.3 H, --COOH or ##STR3## whereby a color change is brought out if hydrogen peroxide is present.
摘要:
The present invention is related to compounds of the general formula (I) ##STR1## wherein R.sup.1 denotes hydrogen, halogen or C.sub.1 -C.sub.4 alkyl andR.sup.2 denotes C.sub.1 -C.sub.4 alkyl, aryl or heteroaryl, or a substituted C.sub.1 -C.sub.4 alkyl, aryl or heteroaryl and their preparation. The compounds can be used in an iron assay system.
