7-methoxy-4-[(4-methoxyphenyl)amino]quinazolin-6-ol

7-methoxy-4-[(4-methoxyphenyl)amino]quinazolin-6-ol corresponds to CAS 1165930-75-5, formula C16H15N3O3, and molecular weight 297.31. The registry number returns one PubChem entry, CID 42645611. PubChem represents the connectivity as SMILES COC1=CC=C(C=C1)NC2=NC=NC3=CC(=C(C=C32)O)OC and assigns InChIKey MOBLCCVQHBHBDB-UHFFFAOYSA-N. The verified graph is one uncharged molecular component.

Its central scaffold is quinazoline, a fused bicyclic system containing two ring nitrogens. A hydroxy group occupies position 6 and a methoxy group occupies neighboring position 7. At position 4, an amino linkage connects the heterocycle to a phenyl ring whose own methoxy substituent is para to that connection. The three oxygens therefore occur in two methoxy groups and one hydroxy group, while the third nitrogen is the linking amino nitrogen. This placement separates the record from analogues with a different phenyl attachment or quinazoline substitution pattern.

A precise Rlavie inquiry should provide CAS 1165930-75-5, the full bracketed name, and the requested quantity, together with a MOL or SDF structure file. The file can be reconciled with PubChem CID 42645611, the long-form SMILES, and InChIKey MOBLCCVQHBHBDB-UHFFFAOYSA-N before request-specific details are considered. Both methoxy locations matter: one belongs to the quinazoline ring and the other to the attached phenyl ring. Retaining those placements and the 6-hydroxy locant helps prevent a similarly named substituted quinazoline from being treated as this exact record.
