What is O-Phenanthroline?
Part I: Introduction
With the progress of science and technology and the development of society, chemical products have invariably permeated our daily lives, in medicine, food, cosmetics, electronics, industry, and other areas, becoming an essential part of our lives. One such product is o-Phenanthroline which has developed particularly rapidly in recent years. Do you know about O-Phenanthroline?
The official answer: 1,10-Phenanthroline monohydrate is an organic intermediate, white crystalline powder. 1,10-Phenanthroline monohydrate is a redox indicator, reagent for the determination of ferrous iron, palladium, vanadium, copper, and iron.
What’s the application of O-Phenanthroline?
Part 2: In-depth development
A common ligand for the spectroscopic determination of metals and the spectroscopic analysis of CO2 reduction. Used in Cu(II)-catalyzed cross-linking reactions of organoboron acids, etc. Also used as a redox indicator and as a reagent for the determination of ferrous titania. Forms complexes with iron, copper, cobalt, nickel, and 2,2′-bipyridine, and red complexes with Fe2+, which are oxidized with potassium permanganate to give 2,2′-dipyridyl-3,3′-dicarboxylic acid. It can be used as a quantitative colorimetric reagent for copper and iron, and as an indicator for the titration of iron salts with cerium sulfate; it can also be used as a dye for animal fibers. The o-phenanthroline-Fe(II) indicator can be prepared by dissolving 1.485 g of the o-phenanthroline monohydrate and 0.695 g of FeSO4?7H2O in 100 mL of water. Indicator for the titration of iron salts with sulfur acid high cerium. A related ligand is a red phenanthroline (BPT), 4,7-diphenyl-1,10-o-phenanthroline. O-phenanthroline can also be used for the analysis of the content of lithium alkyl compounds. The procedure is to allow the sample to interact with a small amount (approximately 1 mg) of o-phenanthroline, which takes on a dark color, and then titrate with alcohol until a colorless titration endpoint is reached. In solutions of pH=2~9, o-phenanthroline reacts chromogenically with 2-valent ferrous ions (Fe2+). The reaction is highly selective and the resulting orange-red complex is very stable, lgK stable=21.3 (20°C) and its solution has a maximum absorption peak at 510nm (visible light). Using this color development reaction, trace amounts of iron can be determined by visible light spectrophotometry.
