Used as a deuterated compound in pharmaceutical research to study drug metabolism and pharmacokinetics, providing insights into the behavior of non-deuterated analogs. It serves as a stable isotope-labeled internal standard in mass spectrometry for accurate quantification of target analytes. In organic synthesis, it acts as a building block for creating complex molecules with deuterium incorporation, enhancing the study of reaction mechanisms. Its application in NMR spectroscopy aids in structural elucidation due to the distinct signals produced by deuterium atoms. Additionally, it is employed in the development of deuterated drugs to improve metabolic stability and reduce side effects.
