Deuterated chloroform (CDCl3), also known as chloroform-d, is an isotopically enriched form of chloroform (CHCl3) in which most its hydrogen atoms consist of the heavier nuclide deuterium (heavy hydrogen) (D = 2H) rather than the natural isotopic mixture in which protium (1H) is predominant. <> Archives Internationales de Pharmacodynamie et de Therapie., "NMR Chemical Shifts of Trace Impurities: Common Laboratory Solvents, Organics, and Gases in Deuterated Solvents Relevant to the Organometallic Chemist", The Theory of NMR – Solvents for NMR spectroscopy,, Pages using collapsible list with both background and text-align in titlestyle, Articles containing unverified chemical infoboxes, Articles with unsourced statements from August 2020, Creative Commons Attribution-ShareAlike License, This page was last edited on 9 November 2020, at 22:08. RIDADR: UN 1219 3/PG 2. Commercial chloroform-d does, however, still contains a small amount (0.2% or less) of non-deuterated chloroform; this results in a small singlet at 7.26 ppm, known as the residual solvent peak, which is frequently used as an internal chemical shift reference. <.

Tables of 1H and 13C NMR chemical shifts have been compiled for common organic compounds often used as reagents or found as products or contaminants in deuterated organic solvents.

This makes 13C-NMR much less senstive than carbon NMR. [citation needed], The properties of CDCl3 are virtually identical to those of regular chloroform, although biologically, it is slightly less toxic to the liver than CHCl3, due to its C–D bond, which is stronger than a C–H bond, making it somewhat less prone to form the destructive trichloromethyl radical (•CCl3).[5]. <> Titanium, iso-Pr alc.triethanolamine complexes.
