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. It has been used in the preparation of sulfide standards for the quantitative analysis of sulfides in raw wastewater (sewage) samples.
It serves as a catalyst during synthesis of thioamides.
Application: Sodium sulfide nonahydrate has been used as a standard for the quantification of volatile sulfur compounds in cheese samples by gas chromatography. 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. Sodium sulfide nonahydrate may be used as a reducing agent for the conversion of vic-dibromides to the corresponding olefins via reductive debromination.
General description: Sodium sulfide nonahydrate participates in the conversion of nitroxides to amines, via reduction.
