6-Amino-7-methoxyquinazolin-4(3H)-one is identified by CAS 130017-55-9 and molecular formula C9H9N3O2. PubChem records the same compound as CID 135743707. Its structure is represented by SMILES COC1=C(C=C2C(=C1)N=CNC2=O)N and InChIKey LDAFKKJLCAHBBB-UHFFFAOYSA-N. These references align on one molecular graph and provide complementary numeric, compositional, and structure-derived identifiers.
The quinazolinone framework contains a fused aromatic ring system with three nitrogen atoms across the complete formula. The amino substituent is fixed at position 6, the methoxy group at position 7, and the carbonyl-containing 4(3H)-one form at position 4. The formula counts nine carbon atoms, nine hydrogens, three nitrogens, and two oxygens. One oxygen belongs to the methoxy group and the other to the ring carbonyl. The official connectivity is a single component and does not include a separate counterion. The 3H notation also forms part of the recorded identity rather than a removable catalog qualifier.
For an inquiry about this exact record, cite the full locanted name together with CAS 130017-55-9 or PubChem CID 135743707. Including the requested quantity and contact details helps distinguish the request from related amino- or methoxyquinazolinones. Rlavie can then map the inquiry to the identifiers shown here and review any requested analytical documentation. Before sending the form, compare the formula C9H9N3O2 and InChIKey LDAFKKJLCAHBBB-UHFFFAOYSA-N with the intended structure. This identifier-led process reduces ambiguity without treating a shortened quinazolinone label as an exact match.
