Dimethylformamide (khutsufatso ea DMF), e tsejoang hape e le N,N-dimethylformamide, ke sebaka sa dimethyl formamide, mme lihlopha tsa methyl ka bobeli li fumaneha liathomong tsa N (nitrogen), kahoo ke lebitso. E le lisebelisoa tsa bohlokoa tsa lik'hemik'hale tse tala le solvent e babatsehang, DMF e sebelisoa haholo ho polyurethane, acrylic, li-additives tsa lijo, meriana, chefo e bolaeang likokoanyana, lidae, lisebelisoa tsa elektronike le liindasteri tse ling.

DMF ke mokelikeli o se nang 'mala le o bonaletsang o nang le ntlha e belang e phahameng, sebaka se tlase sa leqhoa, lik'hemik'hale tse ntle le botsitso ba mocheso, 'me se kopane le metsi le lihlapolli tse ngata tsa tlhaho. Ke solvent e sebelisoang ka tloaelo bakeng sa lik'hemik'hale tsa lik'hemik'hale 'me e bitsoa "sehlaseli sa bokahohleng": DMF e sebelisoa The acrylic fiber e hlahisoang ke mokhoa o omileng oa ho ohla oa motsoako oa acrylic fiber o na le litšobotsi tsa hydrophobicity e ntle, matla a koahelang a matla, mokhoa o bonolo, le maikutlo a matla a letsoho; ha ho etsoa letlalo le entsoeng ka polyester e metsi, DMF e ka sebelisoa e le sesebelisoa sa ho hlatsoa le ho phekola bakeng sa resin ea polyurethane. E sebelisetsoa ho roala lisebelisoa tse sa tšoaneng tse atolositsoeng, 'me ha e sebelisetsoa ho daea letlalo, e ka etsa hore' mala oa seaparo sa letlalo o se ke oa fela; ka lebaka la matla a eona a ho qhibiliha a matla, DMF e sebelisoa e le mokelikeli dae 'me e sebelisetsoa ho daea likhoele tsa maiketsetso, tse ka ntlafatsang ho tšoana ha letlalo. Thepa ea ho daea; joalo ka mokelikeli o ikhethileng o sebelisoang lits'ebetsong tsa karohano, DMF e ka sebelisoa bakeng sa ho monya ka mokhoa o ikhethileng oa li-hydrocarbon tse fapaneng le likhase tsa inorganic. Ka mohlala, DMF e sebelisetsoa ho hlatsoa ethylene ho tlosa acetylene, kahoo e hloekisa ethylene. DMF e ka boela ea sebelisoa ho ntša isoprene, piperylene, joalo-joalo ho tsoa khase ea ho qeta tlhahiso ea semela sa ethylene bakeng sa ho qaptjoa ha resin e sa tsitsang; DMF e ka boela ea sebelisoa e le mokelikeli o khethiloeng bakeng sa mekhoa ea ho ntšoa tšimong ea ho sebetsa ha peterole. Mohlala: lits'ebetsong tsa acid ea polycarboxylic tse nang le thepa e ts'oanang 'me ho thata ho li arola, joalo ka asiti ea isophthalic le terephthalic acid, li ka aroloa habonolo ke ho ntšoa ha solvent DMF kapa stepwise recrystallization.

Liphetohong tsa manyolo, dimethylformamide ha e sebelisoe feela ka mokhoa o pharaletseng e le mokelikeli oa karabelo, empa hape ke karolo ea bohlokoa lipakeng tsa organic synthesis. Ka indasteri ea meriana, e le sethethefatsi sa maiketsetso se mahareng, se sebelisoa haholo tlhahisong ea lithethefatsi tsa doxycycline, cortisone le sulfonamide; indastering ea chefo e bolaeang likokoanyana, e sebelisoa ho kopanya chefo e chefo e phahameng le e chefo e tlase.

E le mokhoa oa ho arabela bakeng sa motsoako oa lik'hemik'hale, DMF e ka sebelisoa e le motsoako oa crystallization bakeng sa tlhoekiso ea meriana. Indasteri ea elektronike, e ka sebelisoa ho lokisa viscosity ea pheko ea li-laminates tsa koporo. DMF e ka boela ea sebelisoa e le mokelikeli oa thepa ho etsa kristale ea polymeric e nang le BF3 (boron trifluoride), e etsang hore BF3 e fetohe ho tloha ho khase ho ea ho e tiileng le e bonolo ho e tsamaisa. Joalo ka polar (hydrophilic) aprotic solvent e nang le ntlha e belang e phahameng, e ka khothaletsa mochine oa bimolecular nucleophilic substitution reaction (SN₂). Ho phaella moo, dimethylformamide e na le phello ea catalytic ho hydrogenation, dehydrogenation, dehydration le dehydrohalogenation reactions, e leng ho fokotsa mocheso oa karabelo le ho ntlafatsa bohloeki ba sehlahisoa.

Ho bonahala eka DMF e tšoaneloa ke sehlooho sa "solvents ea bokahohleng". Mefuta e fapaneng ea ts'ebeliso e tla ba thata ho feta ka nako e khuts'oane.
