May be toxic by ingestion.|N-methylpyrrolidin-2-one is a member of the class of pyrrolidine-2-ones that is pyrrolidin-2-one in which the hydrogen attached to the nitrogen is replaced by a methyl group. It has a role as a polar aprotic solvent. It is a N-alkylpyrrolidine, a lactam and a member of pyrrolidin-2-ones.|N Methyl Pyrrolidone is under investigation for the treatment of Multiple Myeloma.Basic Info-

Air and Water Reactions:Soluble in water.
Reactive Group:Amides and Imides
Reactivity Profile:This amine is a very mild chemical base. It does tend to neutralize acids to form salts plus water. The amount of heat that is evolved per mole of amine in a neutralization is largely independent of the strength of the amine as a base. Amines may be incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides. Flammable gaseous hydrogen is generated by amines in combination with strong reducing agents, such as hydrides.
