RuBP-2S (Ruthenium(bis(bathophenanthroline))(bathophenanthrolinedisulfonate) is a luminescent ruthenium complex similar to RuBPS. Two of the bathophenanthroline ligands are neutral while the third bathophenanthroline ligand is bis-sulfonated, resulting in an overall neutral charge of the ruthenium complex. RuBP-2S shares the spectral properties of RuBPS and may also have similar applications.    &lamba;Ex/&lamba; Em(H2O)= 462 (broad)/603 nm  Yellow solid soluble in water  Store at 4°C and protect from light  C72H46N6O6RuS2  MW: 1256.3
