A colourless or yellow crystalline compound first obtained by alkaline hydrolysis of indigo.
Chemical formula: NH₂C₆H₄COOH‘There have been many studies of the parent acid of this ester, anthranilic acid, (2-aminobenzoic acid).’
- ‘During 325 nm irradiation, anthranilic acid is rapidly and irreversibly bleached, while NADH emission undergoes only modest reduction.’
- ‘This absorption and emission are consistent with anthranilic acid, which is one of these tryptophan products and which has a particularly high fluorescence quantum yield of approximately 0.5 in organic solvents.’
Mid 19th century anthranilic from Greek anthrax ‘coal’ + anil(being any imine derived from aniline) + -ic.
