Application    
99.9% Hydrogen Sulfide Gas Cylinder        
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.
