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 participate in π-π stacking interactions, enhancing binding affinity to target proteins. Also employed in the preparation of pyrimidine-based derivatives with potential antiviral and antibacterial activities. Its amine functionality allows for easy derivatization, making it valuable in combinatorial chemistry and high-throughput screening for drug discovery.
