Incazelo:
I-Dimethyl disulfide inephunga elibi kakhulu lika-anyanisi. Ayinawo ukunambitheka okumnandi. Ngokumangalisayo, nakuba abaningi bethola iphunga layo lingamukeleki uma liphezulu njengoba kuphawuliwe ngenhla, uma lixutshwe, iphunga layo lichazwa njengelimnandi. I-Dimethyl disulfide ivame ukusetshenziswa kanye nezinye izinto ezinambithekayo emikhiqizweni yokudla, okuhlanganisa ukudla okubhakiwe, ushizi, imikhiqizo yobisi eqandisiwe, imikhiqizo yenyama, amasobho, ukunambitheka okumnandi, ukunambitheka kwezithelo, amaswidi athambile, i-gelatin, ama-pudding, kanye neziphuzo ezidakayo nezingenalo utshwala.

Ukusetshenziswa
Kwezimboni, i-Dimethyl disulfide isetshenziswa futhi njenge-ejenti ye-sulfiding ukuze ivuselele ukusabela ezindaweni zokuhluza uwoyela nakwezinye izimboni. Ine-flash point ephansi engu-16 ℃ (61 °F) eveza izingozi zomlilo ngesikhathi sokusetshenziswa kwe-refinery. Ngenxa yephunga layo elinamandla kanye ne-flash point ephansi, i-Dimethyl disulfide ngokuvamile idinga ukugcinwa ngaphansi kwengcindezi ye-nitrogen ezitsheni ezivaliwe.
I-Dimethyl disulfide inephunga le-sulfur elifana nelegalikhi nezinhlanzi ezibolayo. Ngenxa yephunga elihlukile lamakhemikhali esibabule, afana ne-DMDS, avame ukungezwa kugesi yemvelo kanye ne-propane ukuxwayisa ngokuvuza nokuvikela abantu. Ngakho-ke, iphunga le-DMDS fumigation lingaphambaniswa nokuvuza kwegesi. I-DMDS inomkhawulo wephunga ocishe ube ngu-7 ppb, ongaphansi ngokuphindwe kasishiyagalombili kunezinga elisekelwe empilweni elibhekwa yi-EPA njengeliphephile (55 ppb).
I-Dimethyl disulfide isetshenziswa njengesithako esiphakathi kanye nesithako sokudla ku-anyanisi, ugalikhi, ushizi, inyama, amasobho, ukunambitheka okumnandi kanye nokunambitheka kwezithelo. Isetshenziswa ezindaweni zokuhlanza uwoyela njenge-sulfiding agent. Isetshenziswa ukufaka esikhundleni se-alfa i-2-methylfuran-acrolein ukukhiqiza ukudla. Ihilelekile ekulungiseleleni i-4-(methylthio)phenol. Ngaphezu kwalokho, isetshenziselwa ukufaka esikhundleni se-methyl mercaptan njengesithako sikaphethiloli wejethi. Isetshenziswa ejentini yokunambitheka yokwenziwa kanye ne-corrosion inhibitor. Ngaphezu kwalokhu, isebenza njengesithako esisebenzayo sokubulala inhlabathi kwezolimo.
