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. Also employed in the preparation of pyrimidine-based derivatives with potential antiviral and anti-inflammatory activities. Its structural features make it valuable in optimizing drug candidates for improved metabolic stability and solubility.
