Chloroform-D (D, 99.8%)

Deuterated chloroform is a dense organic solvent with the formula CDCl₃. Due to its weak polarity, chloroform is able to dissolve a wide range of organic compounds, thus making it a widely used solvent in organic chemistry. It has low solubility in water but is often used in conjunction with deuterated methanol as a co-solvent.

The ¹H-NMR spectrum of deuterated chloroform comprises of a singlet at 7.24 ppm (due to CHCl₃) and a H₂O/HDO resonance that generally appears at ~1.5 ppm. ¹³C-NMR spectrum gives rise to a 1:1:1 triplet at 77.26 ppm (vs. TMS).

Cambridge Isotope Laboratories (CIL) is pleased to offer highly enriched and highly pure deuterated chloroform 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.

Two different enrichments are available and options that include added tetramethylsilane (TMS), to serve as a chemical shift reference, or added silver foil, to ensure chemical purity for overseas shipments.

All deuterated chloroform products should be stored between -5 and +5 degrees and away from light and moisture. These products are stable for 6 months from date of order if stored under these conditions. After 6 months, the solvent should be re-analyzed for chemical purity before use.
