1-(2-Methoxy-4-nitrophenyl)pyrrolidin-2-one corresponds to CAS 23196-07-8 and formula C11H12N2O4. PubChem records this identity as CID 129607586, SMILES COC1=C(C=CC(=C1)[N+](=O)[O-])N2CCCC2=O, and InChIKey ISECEYWKXUCZHT-UHFFFAOYSA-N. Its synonyms include the earlier “2-pyrrolidinone” spelling with the same ring and phenyl locants.
The pyrrolidin-2-one nitrogen is bonded to position 1 of a phenyl substituent. Relative to that bond, a methoxy group occupies phenyl position 2 and a nitro group position 4. The lactam carbonyl supplies one oxygen; methoxy supplies another; the nitro group supplies two more, producing O4 in C11H12N2O4. One nitrogen belongs to the lactam ring and the other to nitro. The methoxy oxygen is separated from the lactam carbonyl by the substituted phenyl framework. The charge-separated nitro notation is internal to a single neutral graph, not a counterion. No stereochemistry appears in the official representation.
For an exact inquiry, provide CAS 23196-07-8 and retain both aromatic locants plus the pyrrolidin-2-one position. Add the amount of interest, contact information, and any identity-document query. CID 129607586 or InChIKey ISECEYWKXUCZHT-UHFFFAOYSA-N offers a direct structure check before sending. Rlavie can associate those references with the intended record. This identifier set distinguishes the entry from nitro or methoxy positional isomers and from compounds attached through a different pyrrolidinone atom.
