1-Pyrenesulfonic Acid (sodium salt)

1-Pyrenesulfonic acid is a fluorescent probe. It displays absorption/emission maxima of 346/376 nm, respectively. 1-Pyrenesulfonic acid fluorescence can be quenched by ferric ions and the nitroaromatic compounds and explosive components 2,4-dinitrotoluene (2,4-DNT) and trinitrotoluene (TNT) in aqueous solutions. It has been used in study of reverse micelles, including intermicellar migration of reactants and in the estimation of the number of micelles per cluster. 1-Pyrenesulfonic acid has also been used as a surfactant and dopant in the synthesis of polypyrrole micro- and nanowires.CAS Number: 59323-54-5.
