Dimethylformamide yog cov organic sib xyaw nrog cov tshuaj mis (CH3) 2NC (O) H. Feem ntau sau ua DMF (txawm hais tias lo lus no qee zaum siv rau dimethylfuran, lossis dimethyl fumarate), cov kua tsis muaj kob uas ua rau tsis muaj tseeb nrog dej thiab feem ntau ntawm cov kua dej organic. DMF yog ib hom tshuaj lom neeg rau kev fab tshuaj lom neeg. Dimethylformamide yog tsis muaj ntxhiab tab sis qhov ntsuas cov cuab yeej lossis cov qauv tsis zoo feem ntau muaj cov ntses tsis hnov ​​tsw vim yog impurity ntawm dimethylamine. Raws li nws lub npe qhia, nws yog ib qho kev tso dag ntawm formamide, amide ntawm formic acid. DMF yog cov ncov qaumteb qabteb (hydrophilic) aprotic solvent nrog lub siab kub. Nws ua rau muaj kev tawm tsam uas ua raws cov txheej txheem ncov qaumteb qabteb, xws li kev cuam tshuam SN2.
