Used primarily in research and development, this compound serves as a stable isotope-labeled internal standard in mass spectrometry. It aids in the accurate quantification and identification of similar compounds in complex mixtures, particularly in pharmaceutical and environmental analyses. Its deuterated form enhances precision by reducing interference from non-labeled analogs, making it valuable for studies requiring high sensitivity and specificity. Additionally, it is employed in metabolic studies to trace the pathways and transformations of related chemicals in biological systems.
