General description

Acetonitrile-d3 (Trideuteroacetonitrile, CD3CN) is a deuterated NMR (Nuclear Magnetic Resonance) solvent. Molecular rotational friction coefficient[1] and magnetic relaxation times (T1) for 14N and 2D of CD3CN[2] have been determined. It participates as solvent during the synthesis of 2-phenylindole.[3] It serves as solvent for 1H NMR (Proton Nuclear Magnetic Resonance) and 13C NMR (Carbon-13 Nuclear Magnetic Resonance) spectral studies.[4]

Application

Acetonitrile-d3 has been used as a deuterated solvent for the dissolution of internal standard and sample in qNMR (Quantitative Nuclear Magnetic Resonance) quantification experiments.[5] It has also been used as the deuterated solvent in the synthesis of N-methyl indolylfulgimide, which is studied using UV-pump-IR-probe spectroscopy.[6]
