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 due to its ability to form hydrogen bonds and engage in π-π stacking interactions, enhancing binding affinity to target proteins. Commonly employed in the preparation of antitumor, antiviral, and anti-inflammatory agents. Its scaffold is frequently explored in drug discovery for central nervous system disorders owing to its favorable brain penetration and metabolic stability. Also utilized in the design of selective probes for biochemical assays and target validation studies.
