Deuterated acetonitrile has the formula CD3CN and sometimes is abbreviated as ACN-d3. It is an organic solvent with medium polarity, and is often used along with D2O as a co-solvent in reversed phased LC-NMR applications.
The 1H-NMR spectrum of deuterated acetonitrile is a quintet (e.g., 5 lines) centered at 1.94 ppm (vs. TMSP). The water resonance is typically at a chemical shift of 2.1 ppm. The 13C-NMR spectrum gives rise to a multiplet at 1.39 ppm and a singlet at 128.39 ppm (vs. TMS).
Cambridge Isotope Laboratories (CIL) is pleased to offer highly enriched and pure deuterated acetonitrile for use with high-field, NMR spectroscopy These products are carefully manufactured and packaged so that the introduction of any impurity, including paramagnetic impurities, such as dissolved O2(g), into the product is minimized.
