General description

Sodium sulfide nonahydrate participates in the conversion of nitroxides to amines, via reduction.[1]

Application

Sodium sulfide nonahydrate has been used as a source of H2S, to study the effect of H2S on amyloid fibrils associated with neurodegenerative diseases.[2] It has been used in the preparation of sulfide standards for the quantitative analysis of sulfides in raw wastewater (sewage) samples.[3]
It serves as a catalyst during synthesis of thioamides.[4]
Sodium sulfide nonahydrate has been used as a standard for the quantification of volatile sulfur compounds in cheese samples by gas chromatography.[5] It reacts with 4-(2′-hydroxyaryl)-2-(N,N-dialkylamino)-1,3-dithiolium perchlorates in ethanol at room temperature and boiling ethanol to form 1,3-dithiole-2-thiones and 2′-hydroxyacetophenones, respectively.[6] Sodium sulfide nonahydrate may be used as a reducing agent for the conversion of vic-dibromides to the corresponding olefins via reductive debromination.[7]
