N-Phenylnaphthalen-1-amine

N-Phenyl-1-naphthylamine is a dye that fluoresces strongly when bound to the inner phospholipid bilayer of Gram-negative bacteria. N-Phenyl-1-naphthylamine can be used to measure outer membrane permeability. N-Phenylnaphthalen-1-amine is a fluorescence probe for odorant-binding proteins (OBP) with a dissociation constant of 1.67 μM. N-Phenylnaphthalen-1-amine exhibits an excitation wavelength of 337 nM and an emission wavelength of 407 nM[1][2].
