  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.
