Neocuproine is a methylated derivative of phenanthroline. It is a chelating agents, capable of complexing specifically the copper (I ) ions.

Neocuproine is used for masking of copper at the titrimetric determination of iron in blood serum with ferrozine as a complexing agent for Fe 2 . Since this reaction takes place in the micro range, trace elements such as copper would ( which is also contained in the blood serum) falsify the measurement result.
