Description

General description

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

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.

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.
