6,7-diethoxyquinazolin-4(3H)-one

6,7-diethoxyquinazolin-4(3H)-one has CAS 179246-15-2, molecular formula C12H14N2O3, and molecular weight 234.25. PubChem returns one compound for this CAS, CID 135461400. The verified molecular graph is encoded by SMILES CCOC1=C(C=C2C(=C1)C(=O)NC=N2)OCC; InChIKey CAKNVIMJJNHQLR-UHFFFAOYSA-N points to the same identity. It is represented as a single component.

The quinazolinone framework joins a benzene ring to a nitrogen-containing six-membered ring. A carbonyl at position 4 and hydrogen on the position-3 nitrogen establish the 4(3H)-one form captured by the graph. Two ethoxy substituents sit on adjacent benzene positions 6 and 7. Those groups contribute four carbons and two ether oxygens, while the third oxygen is the ring carbonyl. Both nitrogen atoms belong to the fused heterocycle. This combination of neighboring ethoxy locants and the stated quinazolinone form differentiates the compound from other C12H14N2O3 ring isomers.

To submit a precise inquiry, send Rlavie the full H1, CAS 179246-15-2, and the requested quantity together with a MOL or SDF structure file. The file should retain both 6- and 7-ethoxy attachments and the 4(3H)-one graph so it can be reconciled with PubChem CID 135461400, SMILES CCOC1=C(C=C2C(=C1)C(=O)NC=N2)OCC, and InChIKey CAKNVIMJJNHQLR-UHFFFAOYSA-N. Rlavie can confirm this identity set before request-specific information is considered. The formula verifies composition, but it does not communicate substituent locations or the carbonyl-bearing ring form.
