Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of central nervous system agents. It serves as a building block for bioactive molecules due to its structural similarity to amino acids and aromatic moieties, enabling interaction with biological targets. Commonly employed in research settings for designing novel therapeutics, including potential antidepressants and neuromodulators. Also utilized in the preparation of peptidomimetics and enzyme inhibitors where modified amino acid structures enhance metabolic stability and receptor selectivity.
