3-Fluoro-2-nitrobenzoic acid

3-Fluoro-2-nitrobenzoic acid is identified by CAS 1000339-51-4 and molecular formula C7H4FNO4. PubChem resolves this CAS number uniquely to CID 18915920. The cited public record provides SMILES C1=CC(=C(C(=C1)F)[N+](=O)[O-])C(=O)O and InChIKey BOFKZPXQGAMCDM-UHFFFAOYSA-N. The name, CAS number, formula, CID, SMILES, and InChIKey describe the same compound and form a precise, publicly traceable identity set for this catalog entry.

The benzoic acid ring carries fluorine at position 3 and a nitro group at position 2. That positional statement is captured by the connectivity string, where the carboxylic acid, fluoro substituent, and charged nitro representation all belong to one molecular graph. Formula C7H4FNO4 accounts for one fluorine and four oxygen atoms. The CID and InChIKey distinguish this arrangement from other fluoro-nitrobenzoic acid isomers. The locants should therefore remain attached to their respective substituents whenever the compound name is reproduced.

A reliable reference for this page combines the locants in 3-Fluoro-2-nitrobenzoic acid with CAS 1000339-51-4. PubChem CID 18915920 supplies the matching public structure. The SMILES explicitly represents the nitro group as [N+](=O)[O-] and separately records C(=O)O for the acid group. Comparing those features with formula C7H4FNO4 and InChIKey BOFKZPXQGAMCDM-UHFFFAOYSA-N prevents a differently substituted aromatic acid from being treated as this record. Each identifier points to the same neutral parent structure, without adding a counterion or a second component.
