Chloroform-d

Water peak

The position of the water peak in different deuterated reagents is not the same. The water peak of heavy water is about 4.67 ppm. There is a trend that the more water the low field.
Chloroform-D is less soluble with water and the water content is low, so its water peak near 1.59 ppm. Deuterated acetone is about 2.8 ppm and the deuterated dimethylsulfoxide has a water peak of about 3.4 ppm. If water is added to deuterated acetone, the water peak will gradually move to a low field and eventually stop at about 4.7 ppm.

Application

Reagents for nuclear magnetic instruments

Chemical Properties

colourless liquid

Uses

Chloroform-d may be used in the synthesis of dichlorofluoromethane-d (DCFM).

Uses

Labelled Chloroform, generally in trimethylsilane solution, used in NMR spectroscopy as a solvent. Unlabelled chloroform has been used an an anaesthetic due to its action on the central nervous system .

Uses

Chloroform-d is widely used in the organic solvent for the NMR analysis.

Definition

ChEBI: Deuterated chloroform is a deuterated compound that is an isotopologue of chloroform in which the hydrogen atom is replaced with deuterium. Commonly used as a solvent in proton NMR spectroscopy. It has a role as a non-polar solvent, a NMR solvent and a NMR chemical shift reference compound. It is a deuterated compound and a member of chloromethanes.

General Description

Chloroform-d (Deuterochloroform, CDCl₃), deuterated chloroform, is a 100% isotopically enriched NMR (Nuclear Magnetic Resonance) solvent. It is widely employed in high resolution NMR studies due to its high chemical and isotopic purity. Quantitaive infrared spectral investigations of carbon-deuterium stretching bands of chloroform-d in various organic solvents have been reported. Raman difference spectroscopic studies of mixtures of chloroform-d and liquid chloroform have been conducted to evaluate frequency shifts in the in the ν₁ and ν₂ bands of CHCl₃ and CDCl₃.
