Used primarily in pharmaceutical research, this compound serves as a deuterated analog in drug development studies, particularly for metabolic and pharmacokinetic investigations. Its incorporation into molecules helps track and analyze drug behavior in biological systems through isotope labeling. Additionally, it is utilized in the synthesis of active pharmaceutical ingredients (APIs) where deuterium substitution can enhance stability and efficacy. It also finds application in organic synthesis as a building block for creating complex pyrimidine-based compounds.
