Used primarily in research and clinical studies, this compound serves as a stable isotope-labeled internal standard in analytical chemistry. It aids in the accurate quantification and detection of amphetamine and related substances in biological samples, such as urine or blood, using techniques like mass spectrometry. Its application is crucial in forensic toxicology for identifying drug abuse and in pharmacokinetic studies to understand drug metabolism and distribution in the body. Additionally, it supports the development of diagnostic methods and therapeutic monitoring in medical settings.
