NaSH with cas number 16721-80-5 is a flaky solid
Colorless needle-like crystals. Deliquescence. At the melting
point, hydrogen sulfide is liberated. Easily soluble in water and
alcohol. The aqueous solution is strongly alkaline. It reacts with
acid to generate hydrogen sulfide. Bitter taste. Used in the dye
industry to synthesize organic intermediates and to prepare
auxiliaries for the preparation of sulfur dyes, in the leather
industry for dehairing and tanning of hides, in the chemical
fertilizer industry to remove monomer sulfur in activated carbon
desulfurizers, and in the mining industry for copper It is used for
sulphurous acid dyeing in ore dressing and man-made fiber
production. It is the raw material for the manufacture of
semi-finished products of ammonium sulfide and pesticide ethyl
mercaptan. It is also used for wastewater treatment. It is obtained
by absorbing hydrogen sulfide gas from alkali sulfide or caustic
