Dimethyl sulfoxide (nke a kpọchiri akpọchi DMSO) bụ ihe mejupụtara organic nwere sulfur; usoro molekul: (CH3) 2SO; Ọ na-egosipụta dị ka mmiri na-enweghị agba, isi, hygroscopic na mmiri na-enwu enwu na okpomọkụ ụlọ. Ọ nwere ma polarity dị elu yana ebe esi mmiri. Ọ nwekwara njirimara aprotic na mmiri na-agwakọta. Ọ nwere obere nsí, ezigbo nkwụsi ike okpomọkụ, a naghịkwa agwakọta ya na paraffin. Ọ na-agbaze na mmiri, ethanol, propanol, ether, benzene na chloroform na ọtụtụ ụdị ihe organic ndị ọzọ a na-akpọkwa ya "ihe mgbaze zuru ụwa ọnụ." Ọ bụ ihe mgbaze organic nkịtị nke nwere ike ịgbaze kachasị. Ọ nwere ike ịgbaze ọtụtụ ihe organic gụnyere carbohydrates, polymers, peptides, yana ọtụtụ nnu na gas na-adịghị mma. Ọ nwere ike ịgbaze ụfọdụ solute nke ibu ya ruru 50-60% nke onwe ya (ihe mgbaze ndị ọzọ a na-agbaze na-agbaze naanị 10-20%), yabụ ọ dị oke mkpa na njikwa ihe nlele yana nyocha ngwa ngwa nke ọgwụ. N'ọnọdụ ụfọdụ, kọntaktị dị n'etiti dimethyl sulfoxide na chloride nwere ike ibute mmeghachi omume mgbawa.
