Used as a precursor in the synthesis of pharmaceuticals, particularly in the development of antiviral and anticancer agents. It serves as a building block in medicinal chemistry due to its structural similarity to natural nucleobases, enabling incorporation into nucleic acid analogs. Also employed in research settings to study enzyme inhibition and metabolic pathways involving thymine metabolism. Its derivatives are explored for their potential in targeted drug delivery systems and as modulators of biological activity in nucleotide-based therapies.
