Lambar CAS: 872-50-4
Tsarin kwayoyin halitta: C5H9NO

Sunan Turanci: N-methyl-2-pyrrolidone
Halaye: N-methylpyrrolidone (NMP a takaice) wani sinadarin nitrogen ne mai sinadarin heterocyclic wanda ke da sinadarin C5H9NO kuma yana tafasa a zafin jiki na 204°C. Ruwa ne mai ɗan ƙamshi na ammonia. Ana iya haɗa shi da ruwa a kowane rabo kuma yana dacewa da kusan dukkan sinadarai masu narkewa (ethanol, ethanol, Acetaldehyde, ketones, aromatic hydrocarbons, da sauransu) gaba ɗaya.
