Anthranilic acid
CAS number 118-92-3
Anthranilic acid is the organic compound with the formula C6H4(NH2)CO2H.
This amino acid is white solid when pure, although commercial samples
may appear yellow. The molecule consists of a benzene ring with two
adjacent functional groups, a carboxylic acid and an amine. Because
these two groups are polar, this organic compound is highly soluble in
water. It is sometimes referred to as vitamin.

Uses
Anthranilic acid 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 (loop diuretics
eg. furosemide) and UV-absorber as well as corrosion inhibitors for
metals and mold inhibitors in soya sauce.
Anthranilic acid can be used in organic synthesis to generate the
benzyne intermediate.
