'''Sodium deuteroxide''' or '''deuterated sodium hydroxide''' is a chemical compound with the formula {{chem2|NaOD|auto=1}} or NaO{{sup|2}}H. IUPAC recommends that the symbol for deuterium should be {{sup|2}}H,<ref>{{cite web |title=Provisional Recommendations |id=§ IR-3.3.2 |website=Nomenclature of Inorganic Chemistry |series=Chemical Nomenclature and Structure Representation Division |publisher=IUPAC |url=http://www.iupac.org/reports/provisional/abstract04/connelly_310804.html |access-date=2024-08-01 |url-status=dead |archive-url=https://web.archive.org/web/20061027174015/http://www.iupac.org/reports/provisional/abstract04/connelly_310804.html |archive-date=27 October 2006}}</ref> although most chemists use the term NaOD. It is a white solid very similar to sodium hydroxide, of which it is an isotopologue. It is used as a strong base and deuterium source in the production of other deuterated compounds. For example, reaction with chloral hydrate gives deuterated chloroform,<ref>{{cite journal|doi=10.1021/ja01314a058|title=Chloroform-d (Deuteriochloroform)|journal=Journal of the American Chemical Society|volume=57|issue=11|pages=2236–2237|year=1935|last1=Breuer|first1=F.
