Description
4-Methyl-7-(4-nitrophenoxy)-2H-chromen-2-one is a fluorescent coumarin derivative.
1,2 It displays excitation/emission maxima of 323/445 nm, respectively.
1 Unlike the hydrogen sulfide probe 7-(2,4-dinitrophenoxy)-4-methyl-2H-chromen-2-one , 4-methyl-7-(4-nitrophenoxy)-2H-chromen-2-one does not undergo an increase in fluoresence intensity in the presence of sulfur-containing molecules.
