    Applications

    1. Production of thioorganic compounds:
    Several organosulfur compounds are produced using hydrogen sulfide. These include methanethiol, ethanethiol, and thioglycolic acid.
    2. Analytical chemistry:

    For well over a century, hydrogen sulfide was important in analytical chemistry, in the qualitative inorganic analysis of metal ions.

    3. Precursor to metal sulfides:

    As indicated above, many metal ions react with hydrogen sulfide to give the corresponding metal sulfides.
    4. Miscellaneous applications:

    Hydrogen sulfide is used to separate deuterium oxide, or heavy water, from normal water via the Girdler sulfide process.
