Use | Used as an intermediate in organic synthesis. It can also be used as a color filter reagent and a growth inhibitor for seaweed. |
Production method | is obtained by the reaction of anthranilic acid and nitrobenzene. The anthranilic acid and potassium hydroxide are mixed and ground, then nitrobenzene is added to make a paste, and the reaction is at 160 ℃ for about half an hour. The finished product is obtained by separation and purification. The yield is about 6%. |
