What is potassium ferricyanide?

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  Potassium ferricyanide which has developed particularly rapidly in recent years. Do you know about  Potassium ferricyanide?

The official answer:  Potassium ferricyanide is an inorganic substance with the chemical formula K3[Fe(CN)6], commonly known as red blood salt and potassium red blood salt, with a molecular weight of 329.24. It is a red crystal, soluble in water, with yellow-green fluorescence in an aqueous solution, and contains the ferricyanide ligand ion [Fe(CN)6]3-.

Potassium ferricyanide was discovered by the German chemist Leopold Gmelin in 1822, and the composition and crystallisation of potassium ferricyanide were successfully determined by the German chemist Robert Wilhelm Bentham in 1846. The main applications are in photographic paper, pigment, tanning, printing, pharmaceutical, fertiliser, mordant, electroplating, paper, steel and other industries. The central atom of the substance is the iron ion (Fe3+), the ligand is the cyanide ion (CN-) with a coordination number of 6. The inner boundary is the ferricyanide ion {[Fe(CN)6]3-} and the outer boundary is the potassium ion (K+).

What’s the application of Potassium ferricyanide?

It is used for printing plates, oxidation, bleaching and colouring of colour cinema film, blue chart paper and pharmaceuticals, also for electroplating, tanning, papermaking and soap making, etc. It is used for printing plates, oxidation, bleaching and colouring of colour cinema film, photographic printing and development, blue chart paper, pharmaceuticals (antibacterial synergist, PMP, etc.) and blue scribing powder for sanction cutting.

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.
