Cyclohexanol-d12 is primarily used in research and analytical applications as a deuterated solvent or internal standard in nuclear magnetic resonance (NMR) spectroscopy. Its deuterated form helps in reducing background noise, enhancing the clarity of NMR spectra, and enabling precise analysis of molecular structures. It is also employed in studies involving isotopic labeling to trace chemical reactions and pathways, particularly in organic chemistry and biochemistry. Additionally, it serves as a reference compound in mass spectrometry for accurate identification and quantification of substances. Its stability and isotopic purity make it valuable in advanced scientific investigations.
