This compound is primarily used in organic synthesis as a versatile intermediate. Its bromoethyl group makes it a valuable building block for constructing more complex molecules, particularly in pharmaceutical research. It is often employed in the development of active pharmaceutical ingredients (APIs) due to its ability to introduce functional groups into target molecules. Additionally, it serves as a precursor in the synthesis of liquid crystals, which are essential components in display technologies like LCDs. Its benzonitrile moiety also makes it useful in the preparation of agrochemicals and dyes, where specific aromatic structures are required.
