Methane-d4

Description:
Methane-d4, also known as deuterated methane, is a stable isotopologue of methane where all four hydrogen atoms are replaced by deuterium, a heavier isotope of hydrogen. Its chemical formula is CD4, and it has a molecular weight of approximately 18.03 g/mol. Methane-d4 is a colorless, odorless gas at room temperature and pressure, similar to its non-deuterated counterpart. It is primarily used in scientific research, particularly in nuclear magnetic resonance (NMR) spectroscopy, as a solvent and reference standard due to its unique spectral properties. The presence of deuterium alters the vibrational frequencies of the molecule, making it useful for studying reaction mechanisms and molecular dynamics. Methane-d4 is also employed in various applications in organic chemistry and environmental studies, particularly in tracing studies and isotopic labeling. As with all methane derivatives, it is flammable and should be handled with care in controlled environments.
