7-(2,4-Dinitrophenoxy)-4-methyl-2H-chromen-2-one (Compound 1) is a fluorescent probe for the detection of hydrogen sulfide ( H 2 S ). 7-(2,4-Dinitrophenoxy)-4-methyl-2H-chromen-2-one has a low detection limit (4x10 -6 mol/L), good selectivity and high sensitivity. 7-(2,4-Dinitrophenoxy)-4-methyl-2H-chromen-2-one shows almost no cytotoxicity at concentrations of 150 microg/mL. 7-(2,4-Dinitrophenoxy)-4-methyl-2H-chromen-2-one has the excitation peak of 331 nm, and the emission peak about 385 nm in DMSO solvent. Upon the addition of increasing amounts of HS - , the fluorescence intensity increases obviously at about 392 nm [1] .
