3-(5-amino-3-methyl-2-oxo-2,3-dihydro-1H-1,3-benzodiazol-1-yl)piperidine-2,6-dione

3-(5-amino-3-methyl-2-oxo-2,3-dihydro-1H-1,3-benzodiazol-1-yl)piperidine-2,6-dione is PubChem's Title for CAS 2304753-45-3 and formula C13H14N4O3. The number resolves to one compound, CID 138491540, with molecular weight 274.28. PubChem records SMILES CN1C2=C(C=CC(=C2)N)N(C1=O)C3CCC(=O)NC3=O and InChIKey GMUGHJFEUWPRIQ-UHFFFAOYSA-N. The former benzo[d]imidazole name appears in its official synonyms.

The structure joins a benzodiazolone unit to carbon 3 of a piperidine-2,6-dione ring through benzodiazole nitrogen 1. The fused ring carries an amino group at position 5, a methyl group on nitrogen 3, and a carbonyl at position 2. Two further carbonyls occupy positions 2 and 6 of the piperidine ring, accounting for all three oxygens. The four nitrogens occur in the fused system, its amino substituent, and the dione ring. PubChem assigns no configuration at piperidine carbon 3, so the page must not introduce an R or S label.

A precise Rlavie inquiry should state CAS 2304753-45-3, the preferred benzodiazole name, and the requested quantity. Include a MOL or SDF structure file so the fused-ring nomenclature, three carbonyl positions, and piperidine attachment can be checked against PubChem CID 138491540, the SMILES, and InChIKey GMUGHJFEUWPRIQ-UHFFFAOYSA-N. This graph comparison should precede request-specific information. The benzo[d]imidazole synonym remains a valid cross-reference, but a shortened amino methyl benzimidazolone label would omit the exact dione connection and ring locants.
