n,n-dimethylformamide (DMF) yog ib qho tseem ceeb heev rau cov organic solvent uas muaj kev siv dav hauv ntau qhov chaw. Tshwj xeeb, nws cov kev siv tseem ceeb suav nrog:
Cov kuab tshuaj: DMF yog siv dav ua cov kuab tshuaj hauv cov organic synthesis vim nws cov solubility zoo heev thiab kev ruaj khov tshuaj lom neeg, tshwj xeeb tshaj yog nyob rau hauv cov teb ntawm polymer chemistry, dyes, tshuaj, tshuaj tua kab thiab lwm yam teb.
Cov tshuaj tiv thaiv: Hauv cov tshuaj tiv thaiv organic synthesis, DMF tuaj yeem siv ua cov tshuaj tiv thaiv los txhawb kev tiv thaiv. Piv txwv li, DMF tuaj yeem siv ua cov tshuaj tiv thaiv thiab catalyst hauv kev npaj qee yam amides.
Cov kuab tshuaj electrolyte: Hauv kev siv hluav taws xob, DMF feem ntau siv los ua cov kuab tshuaj electrolyte vim nws muaj kev coj ua siab thiab kev ruaj khov ntawm cov tshuaj lom neeg, thiab siv rau hauv kev npaj cov khoom siv hluav taws xob xws li roj teeb thiab capacitors.
Cov Tshuaj Reagents: Hauv kev tshuaj ntsuam tshuaj, DMF tuaj yeem siv ua cov tshuaj ruaj khov hauv cov roj chromatography los pab cais thiab txheeb xyuas cov tshuaj sib xyaw.

Lwm yam kev siv: Tsis tas li ntawd, DMF kuj tseem siv tau rau hauv tawv hluavtaws, tawv cuav, zaj duab xis, thiab cov khoom siv raw rau kev tsim cov tshuaj tua kab xws li tshuaj tua kab thiab tshuaj tua nroj. Hauv kev lag luam tshuaj, nws tuaj yeem siv los ua cov tshuaj sulfa, doxycycline thiab lwm yam tshuaj.
Hauv kev xaus, n,n-dimethylformamide muaj cov ntawv thov tseem ceeb hauv ntau qhov chaw vim nws cov khoom siv lub cev thiab tshuaj lom neeg tshwj xeeb.
