Used primarily as a key intermediate in organic synthesis, especially in the preparation of pharmaceuticals and agrochemicals. Its bromoethyl group allows for facile alkylation and ring-forming reactions, making it valuable in constructing nitrogen-containing heterocycles. Commonly employed in the development of bioactive molecules, including kinase inhibitors and antitumor agents. Also utilized in material science for modifying polymers and functionalizing surfaces due to its reactivity toward nucleophiles.
