Ammonium sulfide

　　Main Uses

　　Chemical Analysis: Used as a sulfide source for the detection of metal ions (e.g., separating and identifying heavy metal ions by forming characteristic sulfide precipitates).

　　Industrial Field:

　　Used in organic synthesis reactions such as the preparation of sulfur dyes and pharmaceutical intermediates.

　　Used as a depilatory and leather treatment agent in the textile industry (dissolves proteins in hair).

　　Used as a flotation agent in the mineral processing industry to separate certain metal sulfide ores.

　　Other Uses:

　　Used in the preparation of other ammonium salts or sulfides.

　　It has been attempted for use as a fertilizer in agriculture (providing sulfur and nitrogen), but its application is limited due to its unpleasant odor and instability.
