Provided is a metal complex which can be used innapplications, such as catalysts for various chemicalnreactions, information/electronic materials, and the like,nand which especially has a peroxidase-like activity and anhigh activity in phosphodiester hydrolysis. Also, providednis a novel method for analyzing a hydrogen peroxide using anmetal complex having a peroxidase-like activity. A cyclicnphenol sulfide metal complex is produced by bringing a cyclicnphenol sulfide metal complex represented by the formula withnat least one selected from metals of the Groups 8, 1A to 7A,n1B and 3B, and is used as a catalyst for oxidation bynhydrogen peroxide or a catalyst for hydrolysis ofnphosphodiester. Furthermore, hydrogen peroxide is analyzednusing the catalyst for hydrolysis.n n(wherein X 1 represents a hydrogen atom, a hydrocarbon group,na carboxyalkyl group, or a carbamoylalkyl group; Y 1 nrepresents a hydrogen atom, a hydrocarbon group, a nhalogenated hydrocarbon group, a halogen atom, an acyl group,na hydroxyl group, a carboxyl group, an amido group, an aminongroup, a nitro group, a cyano group, a chlorosulfonic acidngroup, an alkoxysulfonyloxy group, or a sulfonic acid group;nZ 1 represents Sm 1 , SO, or SO 2 ; m 1 is an integer of from 1 ton7; n 1 is an integer of from 4 to 8). |
