Inkcazo:
I-Dimethyl disulfide inevumba elibi kakhulu letswele. Ayinavumba elibi. Okumangalisayo kukuba, nangona abaninzi befumanisa ukuba ivumba layo alithandeki xa liphezulu njengoko kuphawuliwe apha ngasentla, xa lixutywe, ivumba layo lichazwa njengelimnandi. I-Dimethyl disulfide idla ngokusetyenziswa kunye nezinye izinto ezinencasa kwiimveliso zokutya, kubandakanya izinto ezibhakiweyo, itshizi, iimveliso zobisi ezikhenkcezisiweyo, iimveliso zenyama, iisuphu, iincasa ezimuncu, iincasa zeziqhamo, iilekese ezithambileyo, i-gelatin, iipudingi, kunye neziselo ezinxilisayo nezingenxilisiyo.

Ukusetyenziswa
Kwimizi-mveliso, iDimethyl disulfide ikwasetyenziswa njenge-sulfiding agent ukuze ikhuthaze iintshukumo kwiindawo zokucoca ioyile nakwezinye iindawo zoshishino. Ine-flash point ephantsi ye-16 ℃ (61 °F) ebangela iingozi zomlilo ngexesha lokusetyenziswa kwe-refinery. Ngenxa yevumba layo elinamandla kunye ne-flash point ephantsi, iDimethyl disulfide idla ngokufuna ukugcinwa phantsi koxinzelelo lwe-nitrogen kwizikhongozeli ezivaliweyo.
I-Dimethyl disulfide inevumba lesalfure elifana nelegalikhi kunye neentlanzi ezibolayo. Ngenxa yevumba elikhethekileyo leekhompawundi zesalfure, ezifana ne-DMDS, zihlala zongezwa kwigesi yendalo kunye nepropane ukulumkisa ngokuvuza nokukhusela abantu. Ke ngoko, ivumba le-DMDS fumigation linokuphoswa njengokuvuza kwegesi. I-DMDS inomlinganiselo wevumba omalunga ne-7 ppb, ongaphantsi ngokuphindwe kasibhozo kwinqanaba elisekelwe kwimpilo elithathwa yi-EPA njengelikhuselekileyo (55 ppb).
I-Dimethyl disulfide isetyenziswa njengesixhobo esiphakathi kunye nesongezo sokutya kwi-anyanisi, igalikhi, itshizi, inyama, iisuphu, iincasa ezimnandi kunye neencasa zeziqhamo. Isetyenziswa kwiindawo zokucoca ioyile njenge-sulfiding agent. Isetyenziswa endaweni ye-alfa 2-methylfuran-acrolein ukuvelisa ukutya. Ibandakanyeka ekulungiseleleni i-4-(methylthio)phenol. Ngaphezu koko, isetyenziswa endaweni ye-methyl mercaptan njengesongezo se-jet fuel. Isetyenziswa kwi-arhente yencasa yokwenziwa kunye ne-corrosion inhibitor. Ukongeza koku, isebenza njengesifunxi-mhlaba esisebenzayo kwezolimo.
