Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors for cancer treatment. It serves as a key building block in creating biologically active molecules due to its ability to form stable amide and amidine bonds. Commonly employed in medicinal chemistry for structure-activity relationship (SAR) studies, especially in optimizing drug candidates targeting inflammatory and oncological pathways. Its hydroxylated amidine structure enhances binding affinity to specific enzyme active sites, improving potency and selectivity.
