Ethyl butyl cyanoacetate is an important raw material for chemical production, which is widely used in medicine, pesticides, dyes and other fields. This article will detail the properties and uses of butyl cyanoacetate.

1. the nature of ethyl butyl cyanoacetate

ethyl butyl cyanoacetate is a colorless transparent liquid with a pungent odor. Its molecular formula is C7H11NO2 and its molecular weight is 141.17. The boiling point of ethyl butyl cyanoacetate is 217 ℃, the density is 1.006g/cm3, the flash point is 94 ℃, the refractive index is 1.4338, and the viscosity is 0.97mPa · s. It is insoluble in water, but miscible with organic solvents such as alcohols and ethers.
the chemical properties of
butyl cyanoacetate are relatively stable, but it is easy to hydrolyze under acidic and alkaline conditions. In addition, it can also react with some metals to form salts.

2. the use of ethyl butyl cyanoacetate

1. pharmaceutical intermediates

of ethyl butyl cyanoacetate is an important pharmaceutical intermediates, can be used for the synthesis of a variety of drugs. For example, it can be used to synthesize the anticancer drug irinotecan and the antiviral drug fapilavir, etc.

2. Pesticide raw material

Butyl cyanoacetate is also a common pesticide raw material, which can be used to synthesize a variety of pesticides, fungicides and herbicides. For example, it can be used to synthesize the insecticide imidacloprid and the fungicide prochloraz, etc.

3. dye raw material

butyl cyanoethyl acetate can also be used for the synthesis of dyes, such as acid dyes, direct dyes, etc. These dyes are widely used in textile, printing and dyeing, leather and other industries.

In conclusion, as an important raw material for the production of chemicals, butyl cyanoacetate has been widely used in medicine, pesticides, dyes and other fields. Understanding its nature and use is of great significance for the rational use of resources and the improvement of production efficiency.
