General description 4-(Phenylazo)benzoic acid (PABA), an azobenzene derivative, is a photo-isomerisable molecule. It can be synthesized by reacting p-aminobenzoic acid with interaction of PABA with TiO 2 and ZnO electrodes has been investigated. A photoreversible switch has been developed using dimethylamino calix[4]arene and PABA. 4-(phenylazo)aniline: ChEBI ID CHEBI Definition Azobenzene substituted at one of the 4-positions by an amino group. Stars This entity has been manually annotated by the ChEBI Team. Supplier Information. It exists in two isomeric forms i.e. 1,2,4-triazole and 1,2,3-triazole and used as core molecule for the design and synthesis of many medicinal compounds. 1,2,4-Triazole possess broad spectrum of.
