Origin: Formed within English, by compounding; modelled on a German lexical item. Etymons: phenanthrene n., quinoline n.

Etymology: < phenanthr- (in phenanthrene n.) + -oline (in quinoline n.), after German Phenanthrolin (Z. H. Skraup 1882, in Berichte der Deutsch. Chem. Ges. 15 895).

Chemistry.

Each of a number of isomeric, crystalline, heteroaromatic compounds having the formula C₁₂H₈N₂, whose molecules have a tricyclic phenanthrene ring system in which one CH group in each of the two outer rings is replaced by a nitrogen atom; esp. (in full 1,10-phenanthroline), the ortho isomer, which is used as an indicator for iron, with which it forms a red-orange complex.
