For this entry, CAS Registry Number 83199-81-9 corresponds to the molecular formula C7H7NO3. PubChem resolves the CAS to CID 45082079 and labels that record 3-Methyl-1-oxo-1lambda~5~-pyridine-2-carboxylic acid. The page name 3-methyl-1-oxidopyridin-1-ium-2-carboxylic acid is therefore supported by a consistent set of external and on-page identifiers that can be reviewed together.
This record’s SMILES is CC1=C([N+](=CC=C1)[O-])C(=O)O, and its InChIKey is GWTAIBYPPWDZJW-UHFFFAOYSA-N. PubChem supplies the IUPAC name 3-methyl-1-oxidopyridin-1-ium-2-carboxylic acid. When considered with the CAS number and formula, these identifiers support one unambiguous compound record. A name alone may not expose every difference, so the full identifier set should be considered together.
For a request involving a close variant, provide a CAS number, formula, or structure representation along with the preferred name. These fields make it possible to compare the request with the identifier set displayed here. The page is a reference for 3-methyl-1-oxidopyridin-1-ium-2-carboxylic acid identity data, while further clarification belongs in the enquiry process. For the methyl oxidopyridinium acid, retain both the carboxylic-acid position and the N-oxide notation. The SMILES carries the charged oxygen and carboxyl group in one graph. CID 45082079 is the external record matched by CAS 83199-81-9. That combination is more exact than relying on a shortened pyridine name.
