In 1840-1841, ] was able to extract and crystallize two acids from the products of reaction of ] with ], which he called chrysanilic and anthranilic acids after their colors before purification (golden yellow and black respectively) and the plant anil ('']'').<ref>{{Cite journal |last=Fritzsche |first=J. |date=1841 |title=Ueber die Producte der Einwirkung des Kali auf das Indigblau |url=https://books.google.com/books?id=-l42AQAAMAAJ&pg=PA67 |journal=Journal für Praktische Chemie |language=en |volume=23 |issue=1 |pages=67–83 |doi=10.1002/prac.18410230104 |issn=0021-8383}}</ref><ref>{{Cite journal |last=Fritzsche |first=J. |date=1841 |title=Ueber die Produkte der Einwirkung von Kali auf Indigblau |url=https://books.google.com/books?id=OsMwAAAAYAAJ&pg=PA76 |journal=Justus Liebigs Annalen der Chemie |language=en |volume=39 |issue=1 |pages=76–91 |doi=10.1002/jlac.18410390104 |issn=0075-4617}}</ref> The former was identified as ortho-carboxy anil of indoxyl-2-aldehyde only in 1910<ref>{{Cite journal |last=Sheibley |first=Fred E. |date=March 1943 |title=Carl Julius Fritzsche and the discovery of anthranilic acid, 1841 |url=https://pubs.acs.org/doi/abs/10.1021/ed020p115 |journal=Journal of Chemical Education |language=en |volume=20 |issue=3 |pages=115 |doi=10.1021/ed020p115 |issn=0021-9584}}</ref> while the latter was identified as salicylamide already in 1843 by ].<ref>{{Cite book |url=https://books.google.com/books?id=DAcAAAAAMAAJ&pg=PA536 |title=The Chemical Gazette |date=1843 |language=en}}</ref>

==Production==
Many routes to anthranilic acid have been described. Industrially it is produced from ], beginning with amination:
:C<sub>6</sub>H<sub>4</sub>(CO)<sub>2</sub>O + NH<sub>3</sub> + NaOH → C<sub>6</sub>H<sub>4</sub>(C(O)NH<sub>2</sub>)CO<sub>2</sub>Na + H<sub>2</sub>O
The resulting sodium salt of phthalamic acid is decarbonylated via a ] of the amide group, induced by ]:<ref>{{Cite book | doi = 10.1002/14356007.a03_555| chapter = Benzoic Acid and Derivatives| title = Ullmann's Encyclopedia of Industrial Chemistry| year = 2000| last1 = Maki| first1 = Takao| last2 = Takeda| first2 = Kazuo| isbn = 3527306730}}.</ref>
:C<sub>6</sub>H<sub>4</sub>(C(O)NH<sub>2</sub>)CO<sub>2</sub>Na + HOCl → C<sub>6</sub>H<sub>4</sub>NH<sub>2</sub>CO<sub>2</sub>H + NaCl + CO<sub>2</sub>
A related method involves treating ] with sodium ] in aqueous sodium hydroxide, followed by neutralization.<ref>''Vogel's Textbook of Practical Organic Chemistry, 4th Ed.'', (B. S. Furniss et al., Eds.) (1978), p.666, London: Longman.</ref> In the era when ] was obtained from plants, it was degraded to give anthranilic acid.

Anthranilic acid was first obtained by base-induced degradation of indigo.<ref>{{Cite journal | doi = 10.1021/ed020p115| title = Carl Julius Fritzsche and the discovery of anthranilic acid, 1841| journal = Journal of Chemical Education| volume = 20| issue = 3| pages = 115| year = 1943| last1 = Sheibley| first1 = Fred E.| bibcode = 1943JChEd..20..115S}}</ref>

===Biosynthesis===

Anthranilic acid is biosynthesized from ] by the action of ]. In organisms capable of tryptophan synthesis, anthranilate is a precursor to the ] ] via the attachment of ] to the ]. After then, cyclization occurs to produce ].
