Used as a stable isotope-labeled compound in metabolic research to trace biochemical pathways, particularly in studies of the citric acid cycle and fatty acid synthesis. Its 13C enrichment allows precise tracking of carbon flow in cellular metabolism using techniques like NMR spectroscopy and mass spectrometry. Commonly employed in isotopic labeling experiments to investigate metabolic flux in cancer cells, microorganisms, and plant systems. Also utilized in the synthesis of labeled pharmaceuticals and in environmental studies to monitor degradation pathways of organic compounds.
