Used in organic synthesis as an intermediate for pharmaceuticals and agrochemicals. Serves as a building block in the development of bioactive molecules due to the presence of reactive functional groups. The bromophenyl and pyrimidinethione moieties allow for cross-coupling reactions, making it valuable in medicinal chemistry for constructing complex heterocyclic systems. Commonly employed in the preparation of kinase inhibitors and antimicrobial agents. Also utilized in materials science for designing organic semiconductors and optoelectronic materials owing to its conjugated structure and electron-transport properties.
