Application

Bathophenanthrolinedisulfonic acid disodium salt hydrate has been used to measure iron to determine the solubility of iron in the biological sample. It has been used as an iron chelator to grow plants without Fe-EDTA (ethylenediaminetetraacetic acid).

Biochem/physiol Actions

Bathophenanthrolinedisulfonic acid is a metal chelator. It permits iron determination to be made in aqueous medium without need for solvent extraction. It forms a complex with Fe2+ and makes it unavailable to Fe2+ transporter, thereby inhibiting the transport of iron into chloroplasts. Bathophenanthrolinedisulfonic acid is also used in the assay for determining intracellular glutathione.
