METHOD FOR MEASURING HYPOCHLORITE ION
A method for measuring hypochlorite ion, which comprises the steps of: (A) reacting, with hypochlorite ion, a compound represented by the following general formula (I): wherein R 1 represents a 2-carboxyphenyl group which may be substituted; R 2 represents a phenyl group which is substituted with a substituted or unsubstituted amino group; X 1 and X 2 each independently represents either hydrogen atom or a halogen atom; or a salt thereof; and (B) measuring fluorescence of a dearylated compound generated in the aforementioned step (A) or a salt thereof.
1 . A kit for measuring hypochlorite ion, which comprises a compound represented by the general formula (I) or a salt thereof:
wherein R 1 represents a 2-carboxyphenyl group which may be substituted; R 2 represents a phenyl group which is substituted with a substituted or unsubstituted amino group; X 1 and X 2 each independently represents hydrogen atom or a halogen atom; and
a compound represented by the general formula (II) or a salt thereof:
wherein R 3 represents a 2-carboxyphenyl group which may be substituted; R 4 represents a hydroxyphenyl group; X 3 and X 4 each independently represents hydrogen atom or a halogen atom.
2 . The kit according to claim 1 wherein R 2 is 4-aminophenyl group.
3 . The kit according to claim 1 wherein R 4 is 4-hydroxyphenyl group.
4 . The kit according to claim 2 wherein R 4 is 4-hydroxyphenyl group.
