phenanthroline Chem.|fɪˈnænθrəliːn|
[ad. G. phenanthrolin (Z. H. Skraup 1882, in Ber. d. Deut. Chem. Ges. XV. 895), f. phenanthr-en phenanthrene (s.v. phen-, pheno-) + chinoline chinoline, quinoline.]
An organic compound, C12H8N2, whose molecule is a tricyclic phenanthrene ring system in which one CH group in each of the two outer rings is replaced by a nitrogen atom, and the ortho isomer of which is used esp. as an indicator for iron, with which it forms a red-orange complex.
