Used primarily in research and development, this compound serves as a stable isotope-labeled internal standard in mass spectrometry for the quantification of heterocyclic aromatic amines (HAAs) in complex matrices. Its application is crucial in food safety studies, particularly in analyzing cooked meat products, where HAAs are formed during high-temperature cooking processes. The deuterium labeling ensures accurate and precise measurements, aiding in the assessment of potential carcinogenic risks associated with dietary exposure to HAAs. Additionally, it supports metabolic studies to understand the biotransformation and excretion pathways of these compounds in biological systems.
