Anthranilic acid Chemical Properties,Uses,Production
Chemical Properties
White to off white crystalline powder
Uses
Anthranilic acid can be used in organic synthesis to generate the benzyne intermediate. It is used as an intermediate for production of dyes, pigments, and saccharin. It and its esters are used in preparing perfumes to imitate jasmine and orange, pharmaceuticals and UV-absorber as well as corrosion inhibitors for metals and mold inhibitors in soya sauce.
Uses
Dyes, drugs, perfumes, and pharmaceuticals.
Application
2-Aminobenzoic acid is called vitamin L1; it enhances the milk production of cows. The major use of 2-aminobenzoic acid is as an intermediate for dyes. As its occurrence suggests, it is an intermediate for indigo synthesis. Mordant Brown 40 and Vat Violet 13 are other derivatives. 4-Hydroxy-1-methyl-carbostyril [1677- 46-9] is an important derivative used in making dyes and pigments. Its methyl and ethyl esters are used as fragrances for toiletries. In the pharmaceutical industry, it is used as an intermediate for tranquilizers and antiphlogistics.
Definition
ChEBI: An aminobenzoic acid that is benzoic acid having a single amino substituent located at position 2. It is a metabolite produced in L-tryptophan-kynurenine pathway in the central nervous system.

General Description
Odorless white to pale-yellow or tan crystalline powder with a sweetish taste.
Air & Water Reactions
Anthranilic acid may be sensitive to prolonged exposure to air and light. Insoluble in water.
Reactivity Profile
Anthranilic acid is incompatible with strong oxidizers.
Hazard
Questionable carcinogen.
Fire Hazard
Anthranilic acid is combustible.
Safety Profile
Moderately toxic by ingestion and intraperitoneal routes. Experimental reproductive effects. Human mutation data reported. Questionable carcinogen with experimental tumorigenic data. Combustible. When heated to decomposition it emits toxic fumes of NOx.
Purification Methods
Crystallise anthranilic acid from water (charcoal). It has also been recrystallised from 50% aqueous acetic acid. It sublimes in a vacuum. [Beilstein 14 IV 1004.]
