(2E)-2-Butenedinitrile

Description:

(2E)-2-Butenedinitrile, also known as maleonitrile, is an organic compound characterized by its unsaturated dinitrile structure. It features a butene backbone with two cyano (nitrile) groups attached to the second carbon atom, resulting in a linear configuration. This compound is typically a colorless to pale yellow liquid with a pungent odor. It is soluble in polar solvents such as water and alcohols, but insoluble in non-polar solvents. (2E)-2-Butenedinitrile is known for its reactivity, particularly in nucleophilic addition reactions due to the presence of the electron-withdrawing cyano groups, which enhance the electrophilic character of the double bond. It is used in organic synthesis and can serve as an intermediate in the production of various chemicals, including pharmaceuticals and agrochemicals. Safety precautions are necessary when handling this compound, as it can be toxic and irritant to skin and respiratory systems. Proper storage in a cool, dry place away from incompatible materials is essential to maintain its stability.
