4-(4-Methoxyphenyl)thieno[2,3-b:5,4-c']dipyridine-2-carboxamide

Product Information

4-(4-Methoxyphenyl)thieno[2,3-b:5,4-c']dipyridine-2-carboxamide has CAS 942135-14-0 and molecular formula C18H13N3O2S. PubChem resolves that CAS to exactly one compound, CID 16681705, with molecular weight 335.4. The verified graph is SMILES COC1=CC=C(C=C1)C2=CC(=NC3=C2C4=C(S3)C=NC=C4)C(=O)N, paired with InChIKey NAQZGMVCADAKFA-UHFFFAOYSA-N. It contains one neutral molecular component.

The central fused system combines a thiophene ring with two pyridine rings according to the fusion descriptor thieno[2,3-b:5,4-c']dipyridine. Two nitrogens are embedded in that fused framework, while the third is the carboxamide nitrogen. A carboxamide occupies position 2, and position 4 connects to a phenyl ring bearing methoxy at its para position. Sulfur belongs to the fused thiophene, and the two oxygens are divided between methoxy and carboxamide. The detailed fusion notation and attachment locants are essential because the elemental formula cannot encode the order in which these rings are joined.

When sending an inquiry to Rlavie, include CAS 942135-14-0, the full bracketed name, the requested quantity, and a MOL or SDF structure file. The submitted graph can then be reconciled with PubChem CID 16681705, the complete SMILES, and InChIKey NAQZGMVCADAKFA-UHFFFAOYSA-N before request-specific details are reviewed. Confirmation should cover the two ring-fusion edges, the 2-carboxamide, and the 4-(4-methoxyphenyl) attachment. Omitting the brackets or shortening the name to “thienodipyridine carboxamide” removes the topology that separates this record from another fused heterocycle.
