Application
- Ethylene sulfide is generally used in the preparation of organosulfur compounds, especially for mercaptoethylation of primary and secondary amines to obtain aminothiols.
- It is used in the synthesis of dendritic thioether ligands to stabilize gold nanoparticles (Au NPs).
- Chitosan can be chemically modified by treating ethylene sulfide to obtain a biopolymer for the removal of divalent cations from aqueous solutions.
Ethylene sulfide was used in the chemical modificatoion of biopolymer chitosan.

We have investigated the photofragmentation properties of the three-membered ring heterocyclic molecule ethylene sulfide or thiirane, C(2)H(4)S, by time-of-flight mass spectroscopy. Positive ions have been collected as a function of photon energy around the S K ionization threshold. Branching ratios
