Description and Uses

o-Phenanthroline is a white crystalline powder and serves as an organic intermediate. It has multiple uses, acting as both a redox indicator and a reagent for the determination of various metals such as ferrous, palladium, vanadium, copper, and iron.

o-Phenanthroline is a commonly used redox indicator and also a bidentate ligand. It has been widely used in transition metal-catalyzed cross-coupling reactions and C?H bond activation reactions. It also acts as a chelating agent, forming complexes with most metal ions. In addition, it functions as a ligand employed in the spectrophotometric determination of metals and photocatalytic reduction of carbon dioxide.
