N, N-Dimethylacetamide, uzwi kandi nka acetyldatymumethylamine, cyangwa Dmac kuri make, ni umukunzi wa ponia nyinshi, kandi ukennye cyane, hamwe nibintu bitandukanye byo gufunga. Birakwiye cyane n'amazi, aho ahumura, ester, ketones, inzoga, benzene na chre, kandi birashobora gukora molekile zangiza, bityo zikoreshwa cyane nka solever na catalest. Kubijyanye na Solven, nkigisubizo hamwe nibintu byinshi biteka, ahantu hahanamye, hashobora gukoreshwa ubushyuhe bwa polyacrylonike, hashobora gukoreshwa muri resitine, vinyl pyridine na acide carbolyine na acide carboxy. Ku bijyanye na catalist, irashobora gukoreshwa mu nzira yo gushyushya Urea gutanga aside ya cyacuric, reaction ya Halogide ya Alkyl kugira ngo ikore alkyl alkyne, kandi reaction ya alkyl, hamwe nigisubizo cya Halile na Cyanate kubyara. N, N-Dimethylacetamide irashobora kandi gukoreshwa nkigisubizo cya electrolysise yamashanyarazi namafoto hamwe, gushushanya synthesic, ibikoresho byimiti mbisi, ibikoresho fatizo. Ikibanza gikururwa cyoroshye cyo gutandukanya Styrene kuva C8, nibindi
