Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of kinase inhibitors for cancer treatment. It serves as a building block in the preparation of active pharmaceutical ingredients (APIs) targeting tyrosine kinases and other signaling proteins involved in tumor growth. Its structure allows for selective functionalization, making it valuable in medicinal chemistry for optimizing drug potency and selectivity. Also employed in research for developing new neurodegenerative disease therapies due to its ability to cross the blood-brain barrier in certain derivatives.
