Ua kapa ʻia ʻo N-methylpyrrolidone ʻo NMP, ʻano molekala: C5H9NO, Pelekania: 1-Methyl-2-pyrrolidinone, ʻaʻohe kala o ke ʻano i ka wai melemele māmā, ʻala iki o ka ammonia, hui pū ʻia me ka wai ma kekahi ʻano, hoʻoheheʻe ʻia i loko o ka ether, acetone a me nā mea hoʻoheheʻe organik like ʻole e like me nā esters, halogenated hydrocarbons, aromatic hydrocarbons, a pēlā aku, ua hui piha ʻia me nā mea hoʻoheheʻe āpau, me kahi kiko paila o 204°C a me kahi kiko flash o 91°C. Loaʻa iā ia ka hygroscopicity ikaika a me nā waiwai kemika paʻa. ʻAʻole ia e hōʻino i ke kila kalapona a me ka alumini, a ʻaʻole ia e hōʻino i ke keleawe. ʻAʻole hōʻino iki. Loaʻa iā ia nā pono o ka viscosity haʻahaʻa, ke kūpaʻa kemika a me ka thermal maikaʻi, polarity kiʻekiʻe, volatility haʻahaʻa, a me ka miscibility palena ʻole me ka wai a me nā mea hoʻoheheʻe organik he nui. He lāʻau liʻiliʻi kēia huahana, a ʻo ka palena palena i ʻae ʻia i ka lewa he 100PPM.

Nā ʻano kino a me nā kemika ʻO N-methylpyrrolidone kahi wai melemele ʻole a mālamalama me kahi ʻala ammonia iki. Hiki ke hui pū ʻia me ka wai ma kekahi ʻano a hiki ke hoʻoheheʻe ʻia i nā mea hoʻoheheʻe organik like ʻole e like me ka ether, acetone a me nā esters, nā hydrocarbons halogenated, Chemicalbook aromatics, a pēlā aku, kokoke e hui pū me nā mea hoʻoheheʻe āpau. He paʻa loa ia i ka hopena kūlike ʻole; hoʻoheheʻe mālie ia i loko o ka waikawa hydrochloric i hoʻopaʻa ʻia e hana i ka waikawa 4-methylaminobutyric.
