Popis:	1,3-Bis[di(2-pyridyl)methyleneamino]urea has been examined as a selective Spectrophotometric reagent for copper. It gives a yellow complex with copper in acid medium (pH 1), with an absorption maximum at 400 nm, and molar absorptivity 1.49×1041·mole−1· cm−1. Copper can be quantitatively determined with it in the presence of a large number of ions. The reagent has been applied to the determination of copper in beverages, feeding-stuffs, drugs and alloys.
