Sodium hypoiodite is an inorganic chemical used as an oxidant in various organic chemical reactions. It causes iodination of nitrogen atoms, such 1H-benzotriazole to give 1-iodo-1H-benzotriazole and an imine to give the analogous iodoimine.{{cite book |doi= 10.1055/sos-SD-039-00359|chapter= Product Class 4: Acyclic Dialkyl Sulfoxides and Derivatives|title= Category 5, Compounds with One Saturated Carbon Heteroatom Bond|date= 2008|isbn= 978-3-13-118921-9|editor-last1= Kambe|editor-first1= N.}} It oxidatively cleaves methyl ketones to give iodoform.{{cite journal |doi= 10.1042/bj0940478 |title= Naphthaquinone Biosynthesis in Moulds: The Mechanism for Formation of Javanicin |date= 1965 |last1= Gatenbeck |first1= S. |last2= Bentley |first2= R. |journal= Biochemical Journal |volume= 94 |issue= 2 |pages= 478–481 |pmid= 14348208 |pmc= 1206531 }}
