General description

1,10-Phenanthroline monohydrate is the hydrated form of o-phenanthroline.

Application

1,10-Phenanthroline monohydrate (phen) may be used in the photochemical quantification of Fe3+ and total iron in mineral samples. It may be used as starting reagent for the preparation of 5-nitro-1,10-phenanthroline.
When complexed with copper, it possesses nuclease activity that has been used to study DNA-protein interactions.

Biochem/physiol Actions

Metalloprotease inhibitor; chelates iron, zinc and other divalent metals. Effective concentration 1-10 mM.
