2,5-Dichloroquinoline-3-carbaldehyde

2,5-Dichloroquinoline-3-carbaldehyde is identified by CAS 1064137-50-3 and molecular formula C10H5Cl2NO. Its verified PubChem record is CID 15707529. The structure is represented by SMILES C1=CC2=C(C=C(C(=N2)Cl)C=O)C(=C1)Cl and InChIKey RDFSHUOAFWULQT-UHFFFAOYSA-N. Each identifier matches the corresponding verified structure field for this catalog entry.

The name specifies a quinoline fused ring system containing one ring nitrogen, chlorine substituents at positions 2 and 5, and a carbaldehyde group at position 3. The molecular formula accounts for ten carbon atoms, five hydrogen atoms, two chlorine atoms, one nitrogen atom, and one oxygen atom. The aldehyde carbon and oxygen are included in both the formula and the verified PubChem connectivity. No separate counterion or salt component is present in the recorded SMILES or InChI.

Catalog wording should preserve all three locants because they distinguish this exact connectivity from other dichloroquinoline carbaldehydes. CAS 1064137-50-3, PubChem CID 15707529, molecular formula C10H5Cl2NO, SMILES C1=CC2=C(C=C(C(=N2)Cl)C=O)C(=C1)Cl, and InChIKey RDFSHUOAFWULQT-UHFFFAOYSA-N form the verified identity set. Keeping these values together aligns the page title, molecular formula, and structure record. The CID independently anchors the precise dichloro and aldehyde substitution pattern in PubChem.
