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.

WHY THEY SAY TO US

Peter has been my partner for many years, we met at the Shanghai CPHI Fair in 2014, for the first time I didn't have much interest in Peter's products because our company had a stable supplier. Although we didn't work together, Peter would often send me important news and interesting trend information about the industry, so we became good friends, even though I didn't place any orders with him during this time, even if it was a sample order. In September 2016, our original supplier was unable to provide us with the quality and delivery guarantees we needed, so I first thought of Peter and his company. Until now, we have maintained a very good personal friendship in addition to a steady business relationship.

In all my years of sourcing from China, I first time to found that working with Sincere Chemical was so good, they helped me with all the production and delivery as well as a lot of technical expertise, which saved me a lot of time. When I first approached Peter for a quotation for Optical Brightener, he made me a detailed quotation with not only prices but also foreign trade details, company profile, company strengths, R&D capabilities, production capacity, packaging methods, raw material control, environmental protection, and much more. This information was a very important reference for me in making purchasing decisions. Sincere Chemical is a trustworthy supplier and I believe our business will grow from strength to strength!

Hi, I'm Kim, I'm Peter's partner and although I don't like him very much (because he never gives me more money for my prices, hahaha) I'm still willing to write him customer feedback. As an international buyer, I have to deal with a lot of things every day and my inbox is often full of development letters. It's a lot of junk and meaningless pleasantries, which I don't like that much, but Peter's emails always give me a better understanding of the product and the industry. I am also very pleased with his work ethic, and I am very happy with his work every time I work with him, not only in providing quotations but also in facilitating all the details of my work so that I can concentrate more on other things, so he is the best supplier for me. Although his prices are not the lowest among all suppliers, his products give me the greatest peace of mind.
