What are the main uses of furfurylamine?

The main uses of furfurylamine are as follows:

Medical field

1. Synthetic diuretics: Furfurylamine and 2,4-dichloro-5-sulfamoylbenzoic acid can be condensed to obtain a strong diuretic furosemide, which has a strong and fast diuretic effect and is a commonly used drug for the treatment of severe edema.

2. Synthesis of other drugs: As an important pharmaceutical intermediate, it is used to synthesize a variety of other drugs, such as some compounds with special physiological activities, which may have potential applications in the treatment of cardiovascular diseases, nervous system diseases, etc.

Pesticide field

It can be used to synthesize certain pesticides, such as maltol, which is a pesticide used to prevent and control diseases such as wheat smut.

Material field

1. Synthetic thermosetting resin: 5′-methylenedifurfurylamine (DFA) can be synthesized as a curing agent by reacting furfurylamine with formaldehyde aqueous solution, which is used to prepare all-biobased epoxy thermosetting resins, and has potential applications in aerospace, adhesives, coatings, electronics and construction.

2. Synthesis of other polymer materials: Furfurylamine can participate in the synthesis reaction of some polymer materials, giving the materials special properties, such as improving the heat resistance and mechanical properties of the materials.

Other fields

1. Corrosion inhibitor: Furfurylamine can form a protective film on the metal surface to prevent the metal from contacting with corrosive substances, thereby slowing down the corrosion rate of the metal. It can be used for anti-corrosion treatment of metal products, such as in some chemical equipment, pipelines, metal parts, etc.

2. Flux: During the welding process, furfurylamine can help remove oxides on the metal surface, improve the quality and reliability of welding, and make welding more solid. It is often used in the welding of electronic components and metal products.

3. Organic synthesis intermediate: It is used to synthesize a variety of organic compounds, such as through substitution, addition, condensation and other reactions with other compounds to prepare organic products with different structures and functions. It is one of the important basic raw materials in organic chemical synthesis.
