This compound is primarily utilized in pharmaceutical research and development, particularly in the synthesis of active pharmaceutical ingredients (APIs). It serves as a key intermediate in the production of small molecule drugs, often targeting specific biological pathways or receptors. Its pyrimidine moiety makes it valuable in designing molecules for therapeutic applications, such as kinase inhibitors or antiviral agents. Additionally, it is employed in medicinal chemistry for lead optimization and structure-activity relationship (SAR) studies to enhance drug efficacy and selectivity. Its dihydrochloride form improves solubility and stability, facilitating its use in various experimental and formulation processes.
