Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of purine-based drugs. It serves as a building block for modifying purine structures to create biologically active molecules, including potential antiviral, anticancer, and anti-inflammatory agents. Its bromine functionality allows for further chemical transformations, such as cross-coupling reactions, enabling the introduction of various substituents to tailor biological activity. Commonly employed in medicinal chemistry research for structure-activity relationship studies.
