Used as an intermediate in organic synthesis, particularly in the preparation of pharmaceuticals and bioactive compounds. Its structure allows for incorporation into molecules requiring a substituted aromatic ring with an amino-functionalized ethoxy side chain. Commonly applied in the development of central nervous system agents and receptor modulators due to its ability to mimic certain neurotransmitter scaffolds. Also utilized in the synthesis of dyes and fluorescent probes where the amine group serves as a site for further derivatization.
