Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors and other bioactive molecules. Its structure allows for easy modification and conjugation, making it valuable in medicinal chemistry for designing drug candidates with improved solubility and binding properties. Commonly employed in the preparation of receptor agonists and antagonists, especially in central nervous system and oncology-related research. Also utilized in the creation of labeled derivatives for metabolic and binding studies due to its stable aromatic core and functional handle for derivatization.
