Bathophenanthrolinedisulphonic acid disodium salt hydrate, Hi-ARâ„¢ 1G

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.
