Кислота антраниловая

Химические свойства

White to off white crystalline powder

Использование

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.

Определение

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.

прикладной

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.
