Used in pharmaceutical research as a key intermediate in the synthesis of biologically active compounds, particularly in the development of central nervous system agents and kinase inhibitors. Shows potential in the design of novel therapeutics targeting neurological disorders and certain cancers due to its structural similarity to endogenous neurotransmitters and affinity for specific enzyme active sites. Also employed in the preparation of fluorescent probes for biochemical assays owing to its stable aromatic core and modifiable amine functionality.
