Used primarily in research and analytical studies, this deuterated compound (d3-labeled) serves as a stable isotope-labeled internal standard in mass spectrometry. It aids in the accurate quantification and identification of similar compounds, such as the parent 2-Amino-3,4,7,8-tetramethyl-3H-imidazo[4,5-F]quinoxaline (IQ), in complex biological samples like urine or blood. Its application is crucial in metabolic studies, helping to trace and understand the pathways and transformations of related heterocyclic amines in the body. Additionally, it is employed in the development of analytical methods for food safety, particularly in detecting and quantifying harmful mutagenic substances derived from cooked meats.
