Used primarily in research settings as an intermediate in the synthesis of barbiturate-like compounds. It serves as a building block for developing compounds with potential sedative or anticonvulsant properties. Due to its structural similarity to barbituric acid, it is studied in pharmaceutical chemistry to explore structure-activity relationships in central nervous system depressants. Also employed in analytical chemistry as a reference standard or reagent in assays involving pyrimidine derivatives. Its applications remain largely confined to laboratory and experimental work, with no significant therapeutic use in clinical medicine.
