===Deuterochloroform===
{{Main|Deuterated chloroform}}
[[Deuterated chloroform]] is an [[isotopologue]] of chloroform with a single [[deuterium]] atom. {{chem2|CDCl3}} is a common solvent used in [[NMR spectroscopy]]. Deuterochloroform is produced by the reaction of [[hexachloroacetone]] with [[heavy water]].<ref>{{cite journal |last1=Paulsen |first1=P. J. |last2=Cooke |first2=W.

Deuterochloroform can also be prepared by reacting [[sodium deuteroxide]] with [[chloral hydrate]].<ref>{{cite journal|doi=10.1021/ja01314a058|title=Chloroform-d (Deuteriochloroform)1|journal=Journal of the American Chemical Society|volume=57|issue=11|pages=2236–2237|year=1935|last1=Breuer|first1=F.
