Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors for cancer treatment. It serves as a building block in medicinal chemistry for designing drugs that target specific signaling pathways involved in tumor growth and inflammation. Its structure allows for easy functionalization, making it valuable in creating libraries of compounds for biological screening. Also utilized in research settings to develop potential treatments for neurodegenerative diseases due to its ability to cross the blood-brain barrier in some derivatives.
