Description of Acetylacetone

Acetylacetone is an organic compound that exists in two tautomeric forms that interconvert rapidly and are treated as a single compound in most applications. Although the compound is formally named as the diketone form, pentane-2,4-dione, the enol form forms a substantial component of the material and is actually the favored form in many solvents. It is a colourless liquid that is a precursor to acetylacetonate (acac), a common bidentate ligand. It is also a building block for the synthesis of heterocyclic compounds.

What is Acetylacetone?

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


The official answer: Acetylacetone (acetylacetone) is an organic compound with the molecular formula C5H8O2, which is a colorless or yellowish transparent liquid with the odor of an ester and the property of condensing into shiny crystals when cooled. When subjected to the action of light, it transforms into a brown liquid and produces resin. Used as solvent of cellulose acetate, intermediate of organic synthesis, metal complexing agent, paint desiccant, lubricant, insecticide.

What’s the application of Acetylacetone?

Valid one, also known as acetylacetone, is an intermediate of the fungicides methomyl and pyrimethanil and the herbicide pyrimsulfuron. It is used as the raw material of pharmaceuticals and organic intermediates, and also as a solvent. Used as analytical reagent and extractant of aluminum in tungsten and molybdenum. Acetylacetone is an intermediate of organic synthesis, with guanidine to produce amino-4,6-dimethylpyrimidine, which is an important raw material for pharmaceuticals. It can be used as a solvent of cellulose acetate, additive of gasoline and lubricant, desiccant of paint and varnish, fungicide, insecticide, and so on. Acetylacetone also Chemicalbook can be used as a catalyst for petroleum cracking, hydrogenation and carbonylation reactions, oxygen oxidation promoter, etc. It can be used to remove metal oxides from porous solids and for the treatment of polypropylene catalysts, etc. In Europe and the United States, more than 50% are used in livestock antidiarrheal drugs and feed additives. In addition to the typical properties of alcohols and ketones, it also shows deep red color with ferric chloride and forms chelates with many metal salts. Chemical book is used as metal extractant to separate trivalent ions, paint and ink desiccant, pesticide insecticide, fungicide, the solvent of polymer, reagent for determining thallium, iron, fluorine, and intermediate of organic synthesis, etc. Transition metal chelator. Colorimetric determination of iron and fluorine, determination of thallium in the presence of carbon disulfide; Fe(III) complex titration indicator; used for guanidine group (e.g. Arg) and amino modification in proteins. Used as a transition metal chelator; for the colorimetric determination of iron and fluorine, and thallium in the presence of carbon disulfide. An indicator for iron(III) complexation titrations. Used to modify guanidine groups in proteins and amino groups in proteins.

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.
