This compound is primarily used as a labeled internal standard in analytical chemistry, particularly in mass spectrometry-based assays. Its deuterated form (d5) allows for precise quantification and tracking of similar non-deuterated compounds in complex biological or chemical samples. It is especially valuable in pharmacokinetic studies, where it helps measure drug metabolites or related substances with high accuracy. Additionally, it can be employed in metabolic pathway research to trace and analyze the behavior of specific molecules in biological systems. Its stability and isotopic labeling make it a reliable tool for ensuring reproducibility and reducing analytical errors in sensitive experiments.
