Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of kinase inhibitors for cancer treatment. Its structure allows for functionalization in multi-step reactions, making it valuable in creating active pharmaceutical ingredients (APIs) with targeted biological activity. Commonly employed in research settings for designing compounds with central nervous system (CNS) activity due to its ability to cross the blood-brain barrier. Also utilized in the preparation of fluorinated analogs to improve metabolic stability and bioavailability in drug candidates.
