Used primarily as an intermediate in organic synthesis, especially in the pharmaceutical industry for constructing complex molecules. Its reactive bromoethyl group allows for alkylation reactions, making it valuable in the development of active pharmaceutical ingredients (APIs). Commonly employed in the preparation of beta-blockers and other cardiovascular drugs due to its ability to form nitrogen-containing heterocycles. Also utilized in the synthesis of dyes and functionalized polymers where controlled substitution is required. Its hydrobromide salt form enhances stability and solubility in polar solvents, facilitating easier handling in industrial processes.
