Anthranilic acid is an aromatic acid with the formula C₆H₄(NH₂)(CO₂H) and has a sweetish taste. The molecule consists of a benzene ring, ortho-substituted with a carboxylic acid and an amine. As a result of containing both acidic and basic functional groups, the compound is amphoteric. Anthranilic acid is a white solid when pure, although commercial samples may appear yellow. The anion [C₆H₄(NH₂)(CO₂)]⁻, obtained by the deprotonation of anthranilic acid, is called anthranilate. Anthranilic acid was once thought to be a vitamin and was referred to as vitamin L₁ in that context, but it is now known to be non-essential in human nutrition.
