Dimethylformamide (oo loo soo gaabiyo DMF), oo sidoo kale loo yaqaan N,N-dimethylformamide, waa beddel dimethyl ah oo loogu talagalay formamide, labada kooxood ee methyl-na waxay ku yaalliin atamka N (nitrogen), sidaas darteed waa magac. Maadaama ay tahay walax muhiim ah oo kiimiko ceeriin ah iyo dareere aad u fiican, DMF waxaa si weyn loogu isticmaalaa polyurethane, acrylic, waxyaabaha lagu daro cuntada, daawada, sunta cayayaanka, midabaynta, elektaroonigga iyo warshadaha kale.

DMF waa dareere aan midab lahayn oo hufan oo leh dhibic karkarin sare, dhibic baraf yar, xasilooni kiimiko iyo kuleyl wanaagsan, waana la isku qasi karaa biyaha iyo inta badan dareerayaasha dabiiciga ah. Waa dareere si caadi ah loogu isticmaalo falcelinta kiimikada waxaana loo yaqaan "dareeraha guud": DMF waxaa la isticmaalaa Faybarka acrylic-ka ee ka soo baxa habka wareegga qalalan ee fiilada acrylic-ka ee ku salaysan dareeraha wuxuu leeyahay astaamaha hydrophobicity wanaagsan, awood dabool xooggan, qaab jilicsan, iyo dareen gacan oo xooggan; soo saarista maqaar isku-dhafan oo polyester qoyan, DMF waxaa loo isticmaali karaa sidii wakiil dhaqid iyo bogsiin ah oo loogu talagalay resin polyurethane. Waxaa loo isticmaalaa dahaarka agabyo kala duwan oo la fidin karo, marka loo isticmaalo rinjiyeynta maqaarka, waxay ka dhigi kartaa midabka maqaarka midaysan oo aan libdhin; sababtoo ah awooddeeda milmida xooggan, DMF waxaa loo isticmaalaa sidii dareere midabyo ah waxaana loo isticmaalaa rinjiyeynta fiilooyinka isku-dhafka ah, kuwaas oo hagaajin kara isku-dhafka maqaarka. Astaamaha rinjiyeynta; sida dareere xulasho ah oo loo isticmaalo hababka kala-goynta, DMF waxaa loo isticmaali karaa nuugista xulashada ee hydrocarbons kala duwan iyo gaasaska aan dabiiciga ahayn. Tusaale ahaan, DMF waxaa loo isticmaalaa in lagu dhaqo ethylene si looga saaro acetylene, taasoo nadiifinaysa ethylene. DMF waxaa sidoo kale loo isticmaali karaa in laga soo saaro isoprene, piperylene, iwm. gaaska qiiqa ee wax soo saarka warshadda ethylene si loo sameeyo resin aan dheregsanayn; DMF waxaa sidoo kale loo isticmaali karaa sidii dareere xulasho ah oo loogu talagalay hababka soo saarista ee ku jira habka farsamaynta batroolka. Tusaale ahaan: nidaamyada aashitada polycarboxylic ee leh sifooyin isku mid ah oo ay adag tahay in la kala saaro, sida isophthalic acid iyo terephthalic acid, si fudud ayaa loogu kala saari karaa soo saarista dareeraha DMF ama dib-u-cusboonaysiinta tallaabo-tallaabo.

Falgallada dabiiciga ah, dimethylformamide si weyn looguma isticmaalo oo keliya dareere falgal ah, laakiin sidoo kale waa dhexdhexaad muhiim ah oo ku jira isku-darka dabiiciga ah. Warshadaha dawooyinka, oo ah dhexdhexaad daawo macmal ah, waxaa si weyn loogu isticmaalaa soo saarista daawooyinka doxycycline, cortisone, iyo sulfonamide; warshadaha cayayaanka, waxaa loo isticmaalaa in lagu sameeyo sunta iyo cayayaanka sunta badan leh iyo kuwa aan sunta lahayn.

Iyada oo ah dhexdhexaad falgal ah oo loogu talagalay isku-darka kiimikada, DMF waxaa loo isticmaali karaa sidii dareere crystallization ah oo loogu talagalay nadiifinta daawooyinka. Warshadaha elektaroonigga ah, waxaa loo isticmaali karaa in lagu hagaajiyo daxalka wakiilka daaweynta ee laminates-ka naxaasta ah ee la dahaadhay. DMF waxaa sidoo kale loo isticmaali karaa sidii dareere side ah si loo sameeyo kiristaalo polymeric ah oo leh BF3 (boron trifluoride), taasoo ka dhigaysa BF3 mid ka beddela gaaska una beddela mid adag oo si fudud loo qaadi karo. Iyada oo ah dareere aprotic ah oo polar (hydrophilic) ah oo leh dhibic karkaraya oo sare, waxay kor u qaadi kartaa habka falgalka beddelka nucleophilic (SN₂). Intaa waxaa dheer, dimethylformamide wuxuu leeyahay saameyn katalytic ah oo ku saabsan falgalka hydrogenation, dehydrogenation, fuuq-baxa iyo dehydrohalogenation, taas oo yaraynaysa heerkulka falgalka oo hagaajisa daahirnimada badeecada.

Waxay u muuqataa in DMF ay u qalanto magaca "dareeraha guud". Noocyadan isticmaalka ah way adkaan doontaa in la dhaafo waqti gaaban gudaheed.
