6,7-Bis(2-methoxyethoxy)quinazolin-4(3H)-one is the PubChem Title for CAS 179688-29-0 and molecular formula C14H18N2O5. The registry number returns one compound, CID 135409305, with molecular weight 294.30. PubChem records SMILES COCCOC1=C(C=C2C(=C1)C(=O)NC=N2)OCCOC and InChIKey PMQWTUWLIGJTQD-UHFFFAOYSA-N. Its synonym list explicitly includes the catalog's former 4(1H)-one wording.
The quinazolinone framework is a fused bicyclic system with two ring nitrogens and a carbonyl at position 4. Positions 6 and 7 each carry a 2-methoxyethoxy substituent. Every side chain contributes an aryl ether oxygen and a terminal methoxy oxygen; the carbonyl supplies the fifth oxygen in C14H18N2O5. PubChem's preferred name states the 3H lactam form, while its synonym record links the 1H label to the same CID, SMILES, and standard InChI. The verified graph has one component and no defined stereochemical layer.
For a structure-focused inquiry to Rlavie, provide CAS 179688-29-0, the preferred 3H name, and the requested quantity. Include a MOL or SDF structure file so the carbonyl form and both adjacent side chains can be compared with PubChem CID 135409305, the stated SMILES, and InChIKey PMQWTUWLIGJTQD-UHFFFAOYSA-N. This review should occur before request-specific information is considered. If another source displays the 1H synonym, retain the CID and structure identifiers so the naming difference does not become an unsupported positional or salt-form assumption.
