Decarboxylations - Organic chemistry



According to Wikipedia, fluoride salts are commonly used in biological assay processing to inhibit the activity of phosphatases, such as serine/threoninephosphatases. Fluoride mimics the nucleophilic hydroxide ion in these enzymes' active sites. Beryllium fluoride and aluminium fluoride are also used as phosphatase inhibitors, since these compounds are structural mimics of the phosphate group and can act as analogues of the transition state of the reaction. Diethyl fluoromalonate can be used to various synthesize enzyme inhibitors.

Diethyl fluoromalonate can also be used to prepare fluoride-containing amino acids, fluoride-containing Chalcone, fluorotetrahydroquinolines, and sedative areas.



Environmental friendly and risk free
Banff Green Technoligies, Inc.'s novel manufacturing process is much more environmental friendly than the traditional process. The traditional process emits HF which is extremely toxic and corrosive and a mixture of methylbenzene and triethylamine which are also toxic and difficult to contain. In contrast, Banff Green Technoligies, Inc.'s process does not involve any of these materials. Thus, Banff Green Technoligies, Inc.'s wastes can be easily treated and reach the emission standard.

Higher purity
Banff Green Technoligies, Inc.'s diethyl fluoromalonate can reach as high as 99% purity (by GC), and is the highest assay that is commercially available. The common purity of diethyl fluoromalonate on the market is about 90% and it is difficult to further purify.

Bulk stock
As diethyl fluoromalonate is one of Banff Green Technoligies, Inc.’s most important products, a large stock is available all year round.

If you need quotation or price for diethyl fluoromalonate, please kindly send inquiry to us. Information as MSDS, COA, GC and NMR spectrum are all available upon your request.



Diethyl fluoromalonate is an important intermediate for the synthesis of environment-friendly fungicide Fluoxastrobin developed by Bayer CropScience in 2005. Fluoxastrobin, commonly used in Fandango, Fortix, Scenic, DISARM, EVITO, and HEC 480 SC (trade names), is a new strobilurin fungicide active ingredient for the control of fungal diseases such as early blight, late blight, leaf spots, leaf rust, and Rhizoctonia solani.

The malonic ester synthesis is based on the use of diethyl malonate in order to generate a stabilized carbanion. The carbanion can then react as a nucleophile

Diethyl malonate, a colourless, fragrant liquid boiling at 199 C, is prepared by the reaction of monochloroacetatic acid with methanol, carbon monoxide or by the reaction cyanoacetic acid (the half nitriled-malonic acid) with ethyl alcohol.

The methylene groups in 1,3-dicarboxylic acid utilize the synthesis of barbiturates; a hydrogen atom is removed by sodium ethoxide, and the derivative reacts with an alkyl halide to form a diethyl alkylmalonate.
