Used in pharmaceutical research as a deuterated analog to study drug metabolism and pharmacokinetics. The presence of amino and bromo groups on the pyrazine ring provides potential as a starting material or intermediate in synthesizing biologically active compounds. Its incorporation into compounds helps trace metabolic pathways and understand the behavior of drugs in biological systems. It is particularly valuable in the development of new therapeutic agents, where deuterium labeling enhances stability and extends the half-life of active molecules. Additionally, it serves as a building block in organic synthesis for creating complex molecules with potential biological activity. Its unique deuterated structure makes it useful in NMR spectroscopy and mass spectrometry for detailed structural analysis and precise tracking of biochemical processes.
