Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of kinase inhibitors for cancer treatment. It serves as a building block in the preparation of bioactive molecules due to its ability to mimic purine bases, enabling interactions with enzyme active sites. Commonly employed in medicinal chemistry for structure-activity relationship (SAR) studies to optimize drug candidates. Also applied in the fabrication of organic semiconductors and optoelectronic materials owing to its electron-deficient aromatic structure that supports charge transport properties.
