Useful:

• Canonical SMILES: C1=CC(=C(C=C1F)C(=O)O)C(=O)O
• Chemical Composition and Structure: 4-Fluorophthalic acid is a derivative of phthalic acid which contains a fluorine atom attached to one of the carbon atoms in the phthalic acid structure.
• Uses: Fluorescent Probe: ; Utilized in the synthesis of nitrogen–fluorine co-doped carbon nanodots (N,F-CDs) for the selective detection of hypochlorite ions (ClO?) in aqueous media. The N,F-CDs act as a fluorescent probe, with their fluorescence being quenched in the presence of ClO? ions.^[1]; ; Pharmaceutical Intermediate: ; Used as an intermediate in the synthesis of pharmaceutical compounds.
• Analysis Method: Characterized using techniques such as transmission electron microscopy (TEM) and Fourier transform infrared spectroscopy (FT-IR) to analyze the morphology and chemical structure of the synthesized compound.
