Iodomethane-d₃（Cat No.:R040891）, stabilized with copper wire, is a deuterated methyl iodide where all three hydrogen atoms in the methyl group are replaced with deuterium (²H). This isotopically labeled compound is primarily used in nuclear magnetic resonance (NMR) spectroscopy and mass spectrometry as a methylating agent or tracer. The presence of deuterium allows for precise tracking of methyl groups in metabolic and reaction pathway studies. Copper wire stabilization prevents decomposition and extends shelf life by inhibiting the formation of free iodine. It is highly volatile and must be handled under controlled conditions.
