Used in pharmaceutical research as a key intermediate in the synthesis of tyrosine kinase inhibitors, particularly those targeting cancer pathways such as EGFR and VEGFR. Its structure supports high binding affinity to enzyme active sites, making it valuable in developing anti-tumor agents. Also explored in the design of small-molecule inhibitors for inflammatory and neurodegenerative diseases due to its ability to cross cell membranes and modulate intracellular signaling.
