8-Hydroxyquinoline-2-carboxylic acid is PubChem’s IUPAC name for CID 74079 and is linked to CAS 1571-30-8. Its formula is C10H7NO3, with SMILES C1=CC2=C(C(=C1)O)N=C(C=C2)C(=O)O and InChIKey UHBIKXOBLZWFKM-UHFFFAOYSA-N. PubChem Title “8-hydroxyquinaldic acid” and the catalog name appear together in the official synonym record.
The quinoline system contains two fused rings and one ring nitrogen. A carboxylic acid group is attached at position 2, next to that nitrogen, while a hydroxy group occupies position 8 on the fused benzene portion. Two oxygens form the carboxylic acid and the third belongs to the hydroxy substituent. Ten carbon atoms and seven hydrogens complete formula C10H7NO3. The official structure is a single component without a salt fragment or stereochemical layer. The locants distinguish it from other hydroxyquinoline carboxylic acid arrangements that could share similar wording.
When submitting an inquiry, state CAS 1571-30-8 and the full IUPAC name rather than only the quinaldic acid synonym. Provide the quantity being evaluated, contact information, and any requested identity-document details. CID 74079 and InChIKey UHBIKXOBLZWFKM-UHFFFAOYSA-N supply independent checks on the fused-ring substitution pattern. Rlavie can connect those references to this precise record. Confirming the formula and both positions before sending prevents a shortened hydroxyquinoline label from being interpreted as another isomer.
