2-Butanone-d5 is a deuterated form of 2-butanone, where five hydrogen atoms have been replaced with deuterium. This isotopically labeled compound is commonly used in chemical, environmental, and pharmaceutical research, particularly in studies involving volatile organic compounds (VOCs), solvent behavior, and metabolic pathways. The deuterium labeling allows for precise tracking and analysis in techniques such as mass spectrometry and nuclear magnetic resonance (NMR) spectroscopy, providing enhanced accuracy in detecting and quantifying the compound in various matrices. 2-Butanone-d5 is valuable for researchers studying environmental exposure, metabolic processes involving ketones, and in developing analytical methods for monitoring and controlling VOC emissions.
