N-Phenylanthranilic Acid is also known as Fenamic acid. It is an aromatic organic compound belonging to the aminobenzoic acid family and is the N-phenyl derivative of anthranilic acid. It serves as the parent scaffold for fenamate NSAIDs such as mefenamic acid, flufenamic acid, tolfenamic acid and meclofenamic acid. It is also used as an intermediate in heterocyclic synthesis, including acridone derivatives. It typically appears as a white to pale yellow crystalline solid with limited water solubility but good solubility in organic solvents like ethanol and acetone. It exhibits both acidic and basic character and shows biological activity such as ion channel modulation.

N-Phenylanthranilic Acid is primarily used as an intermediate in pharmaceutical, dye, pigment and organic synthesis. It is also investigated in biochemical and material science research.
N-Phenylanthranilic Acid is also known as fenamic acid, 2-(phenylamino)benzoic acid and 2-anilinobenzoic acid. It is also referred to as N-phenyl-2-aminobenzoic acid or phenyl anthranilic acid.
N-Phenylanthranilic Acid is a direct N-phenyl derivative of anthranilic acid formed by substituting one hydrogen atom of the amino group (-NHâ‚‚) in anthranilic acid (2-aminobenzoic acid) with a phenyl (benzene) ring attached to the nitrogen atom.Â
