This compound is primarily used in environmental and toxicological research as a labeled internal standard for the analysis of metabolites derived from trichloroethylene (TCE) exposure. It aids in the quantification of TCE metabolites in biological samples, such as urine, to assess human exposure and potential health risks. The isotopic labeling (13C and d3) enhances the precision and accuracy of mass spectrometry-based detection methods, allowing for more reliable data in studies related to occupational safety, environmental monitoring, and toxicokinetics. Additionally, it supports the development of analytical methods for understanding the metabolic pathways and detoxification mechanisms of TCE in the body.
