摘要：
Compounds are disclosed which are 4-amino-2,3-di-substituted-1-(mono- or trichlorophenyl)-3-pyrazolin-5-ones represented by the following formulae (1) to (3): ##STR1## and acid addition salts thereof. The compounds can be easily produced and are useful for qualitative analysis or quantitative analysis of hydrogen peroxide when used as a component of a color indicator composition for detecting hydrogen peroxide.
