Used in research and development as a labeled compound for tracing and studying chemical reactions, particularly in organic synthesis and metabolic pathways. It is valuable in nuclear magnetic resonance (NMR) spectroscopy and mass spectrometry for its deuterium atoms, which provide distinct signals for analysis. Applied in the investigation of furan chemistry and the production of furan-based polymers and resins. Also utilized in the development of advanced materials and biofuels. Its isotopic labeling aids in understanding reaction mechanisms and kinetics in both industrial and academic settings.
