Neocuproin is a methylated derivative of phenanthroline . It is a chelate complexing agent that can specifically complex copper (I) ions .
Neocuproin is used to mask copper in 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 (which is also contained in blood serum) would falsify the measurement result.
