Fluorogenic indicator compounds responsive to the presence of hydrogen peroxide and methods and test compositions for determining hydrogen peroxide in a test sample. Preferred indicator compounds are 3,4-dihydrocoumarin derivatives and 3,4-dihydro-2-quinolone derivatives, especially those having a dialkylamino group at the 7-position. Such particularly preferred compounds are of the formula: ##STR1## wherein R.sup.1 is hydrogen, cyano, or --COOR.sup.6, --CONHR.sup.6 or --CON(R.sup.6).sub.2 where R.sup.6 is hydrogen, alkyl, alkenyl, or aryl; R.sup.3 and R.sup.4 are lower alkyl; and Y is .dbd.O or .dbd.N--R.sup.5 where R.sup.5 is hydrogen or lower alkyl. The indicator compounds yield highly fluorescent products upon oxidation by hydrogen peroxide in the presence of a peroxidatively active substance and are useful in analytical systems which generate hydrogen peroxide in response to an analyte under determination in a test sample.
对过氧化氢敏感的荧光指示剂化合物及用于检测试样中过氧化氢的方法和测试组合物。首选的指示剂化合物是3,4-二氢香豆素衍生物和3,4-二氢-2-喹啉衍生物,特别是在7位具有二烷基氨基基团的化合物。这样特别优选的化合物的公式为:##STR1## 其中R.sup.1是氢,氰或--COOR.sup.6,--CONHR.sup.6或--CON(R.sup.6).sub.2,其中R.sup.6是氢,烷基,烯基或芳基;R.sup.3和R.sup.4是较低的烷基;Y是.dbd.O或.dbd.N--R.sup.5,其中R.sup.5是氢或较低的烷基。在过氧化氢存在的过氧化物活性物质存在下,指示剂化合物通过氧化反应生成高度荧光的产物,可用于在试样中检测分析物生成过氧化氢的分析系统。
