Dimethylformamide kyakkyawan maganin narkewa ne ga nau'ikan polymers masu ƙarfi kamar polyethylene, polyvinyl chloride, polyacrylonitrile, polyamide, da sauransu. Ana iya amfani da shi don jujjuyawar jika na zaruruwan roba kamar polyacrylonitrile da haɗa polyurethane; Ana amfani da shi don yin fim ɗin filastik; Hakanan ana iya amfani da shi azaman mai cire fenti don cire fenti; Hakanan yana iya narkar da wasu launuka masu ƙarancin narkewa, yana ba su halayen rini. Ana amfani da Dimethylformamide don cire hydrocarbon mai ƙanshi, da kuma rabawa da dawo da butadiene daga ɓangaren C4 da isoprene daga ɓangaren C5. Hakanan ana iya amfani da shi azaman mai tasiri don raba abubuwan da ba hydrocarbon ba daga paraffin. Yana da zaɓi mai kyau don narkewar isophthalic acid da terephthalic acid: narkewar isophthalic acid a cikin dimethylformamide ya fi na terephthalic acid girma. Cirewar sinadarai ko kuma wani ɓangare na crystallization a cikin dimethylformamide na iya raba su biyun. A cikin masana'antar sinadarai na petrochemical, ana iya amfani da dimethyl formamide azaman mai sha iskar gas don rabawa da tace iskar gas. A cikin halayen halitta, dimethylformamide ba wai kawai ana amfani da shi sosai azaman mai narkewa ba, har ma yana da mahimmanci a cikin haɗakar kwayoyin halitta. Ana iya amfani da shi don samar da chlorpyrifos a cikin masana'antar magungunan kashe kwari; A cikin masana'antar magunguna, ana iya amfani da shi don haɗa pyrimidine iodide, doxycycline, cortisone, bitamin B6, iodoside, Qubijing, thiapyrimidine, N-formyl sarcolysin, antineoplastic acid, methoxyaromaine, bianzapine, cyclohexanone nitrourea, furfurouracil, hemostatic acid, Fenfenmethasone, medroxyprogesterone, biliveratrol, chlorpheniramine, da sauransu. Dimethylformamide yana taka rawa wajen haɓaka hydrogenation, dehydrogenation, dehydration, da dehalogenation halayen, rage zafin amsawa da inganta tsarkin samfurin.

04Maganin titration na maganin ruwa mara ruwa, mai narkewa don resin ethylene da acetylene, haɗin kwayoyin halitta, photometry, yanayin chromatography na gas (matsakaicin zafin aiki 50 ℃, methanol mai narkewa), rabuwa da nazarin hydrocarbons na C2-C5, da ikon raba al'ada, isobutene, cis, da trans butene. Binciken ragowar magungunan kwari. Haɗin kwayoyin halitta. Haɗa peptide. Ana amfani da shi a masana'antar daukar hoto.
