Neocuproine is a aromatic heterocyclic compound and methylated phenanthroline derivative. It can be used for the spectrophotometric determination of copper and chelates cuprous ion in the presence of ferrous ion. The Cu-neocuproine complex consists of two molecules of neocuproine with one cuprous ion, with a maximum absorption at 454 nm (EmM 7.95). A study of the extraction of the Cu-neocuproine complex from acetate buffered aqueous solutions by propylene carbonate has been published.
