Ethane-d5
Ethane-d5 (CAS: 3681-30-9), a deuterated analogue of ethane with the chemical formula CD₃CD₂H, is a valuable isotopically labelled gas. Possessing a molecular weight of 35.10 g/mol, it serves as a critical internal standard and tracer in various analytical techniques, particularly in mass spectrometry and NMR spectroscopy. Its applications extend to chemical synthesis research and studies requiring precise isotopic labelling.
Internal Standard in Mass Spectrometry
Ethane-d5 is frequently employed as an internal standard in gas chromatography-mass spectrometry (GC-MS) and other mass spectrometry techniques. Its similar chemical properties to non-deuterated ethane, combined with a distinct mass, allows for accurate quantification of ethane or related compounds in complex matrices.
NMR Spectroscopy Studies
Due to the presence of deuterium (D), Ethane-d5 is used in Nuclear Magnetic Resonance (NMR) spectroscopy. It can serve as a solvent or a labelled compound to investigate reaction mechanisms, molecular structure, and dynamics where isotopic substitution provides unique spectral information.
Chemical Synthesis and Research
As a deuterated reagent, Ethane-d5 is utilised in synthetic organic chemistry for isotopic labelling studies. This helps researchers elucidate reaction pathways and stereochemical outcomes by tracking the incorporation of deuterated atoms.
Tracer in Environmental Studies
Its isotopic signature makes Ethane-d5 suitable as a tracer in environmental and atmospheric science research. It can be used to track the fate and transport of gaseous compounds or to study atmospheric chemistry processes.
