Description

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.

General description

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