Introduction and application of CAS: 91-40-7 | N-Phenylanthranilic acid
Introduction N-phenylaminobenzoic acid, also known as vanadium reagent, is an important intermediate commonly used in the synthesis of acridine compounds. It can be obtained by coupling 2-chlorobenzoic acid and aniline.
Uses N-phenyl anthranilic acid, a sensitive internal oxidation-reduction indicator. It is especially suitable for the determination of vanadium in steel analysis. It is also known as vanadium reagent. It is an important intermediate commonly used in the synthesis of acridine compounds and is widely used in antimalarial drugs, anti-inflammatory drugs, anti-tumor drugs, etc.
