Anthranilic acid Usage And Synthesis

Chemical Properties

White to off white crystalline powder

Uses

Dyes, drugs, perfumes, and pharmaceuticals.

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.]
