4-Amino-2,5-dichloroquinazoline corresponds to CAS 1107695-06-6, molecular formula C8H5Cl2N3, and molecular weight 214.05. The CAS resolves uniquely to PubChem CID 34181658. PubChem records SMILES C1=CC2=C(C(=C1)Cl)C(=NC(=N2)Cl)N and InChIKey KWONOEUAYOZICR-UHFFFAOYSA-N. The formula and digital identifiers describe one uncharged connectivity without a separate counterion.
Quinazoline is a fused bicyclic framework combining a benzene portion with a diazine ring. In this record, the exocyclic amino group is assigned to position 4, while chlorine atoms occupy positions 2 and 5. The two chlorines are therefore not equivalent generic substituents: one belongs to the nitrogen-containing portion of the fused system and the other lies on the benzenoid portion. The three nitrogen atoms in C8H5Cl2N3 comprise two ring nitrogens and the amino nitrogen. Those placements are encoded directly in the SMILES.
A technical inquiry can identify the target with the complete H1, CAS 1107695-06-6, and a requested quantity, accompanied by a MOL or SDF file. Rlavie can compare the submitted connectivity with CID 34181658 and InChIKey KWONOEUAYOZICR-UHFFFAOYSA-N before addressing information specific to the request. Keeping the 2,5-dichloro locants and the 4-amino locant visible is important because another chloroquinazolinamine can retain a similar formula pattern while placing substituents at different ring atoms. The structure file provides the controlling reference if a shorthand name is ambiguous.
