Sodium hydrosulfide hydrate
Sodium hydrosulfide hydrate (CAS: 207683-19-0) is an inorganic salt with the linear formula NaSH·xH<sub>2</sub>O. It presents as a crystalline solid and is an essential reagent in various chemical synthesis applications. This compound plays a role in the production of other chemicals and is a useful source of sulfide ions in reactions. Supplied by TSS, it is primarily available for the Japanese market.

Chemical Synthesis
Sodium hydrosulfide hydrate is employed as a key reagent in organic and inorganic synthesis. It serves as a source of hydrosulfide ions for nucleophilic substitution reactions and in the preparation of sulfur-containing compounds.
Precursor for Sulfur Compounds
This compound acts as a precursor in the manufacturing of various sulfur-containing chemicals. Its reactivity allows for the introduction of sulfur into organic molecules and the formation of inorganic sulfides.
Depilatory Agent in Leather Tanning
In the leather industry, sodium hydrosulfide is used as a depilatory agent to remove hair from hides and skins. It effectively breaks down the keratin structure of hair, facilitating its removal during the tanning process.
Flotation Agent in Mining
Sodium hydrosulfide hydrate can be used as a flotation agent in the mining industry, particularly for the separation of sulfide ores. It aids in selectively attaching to mineral surfaces, facilitating their recovery.
