General description

4-Methyl-o-phenylenediamine is the 4-substituted derivative of o-phenylenediamine. It reacts with selenous acid in acid solution to form benzoselenadiazoles.

Application

4-Methyl-o-phenylenediamine was employed as chromogenic reagent in the spectrophotometric determination of selenium(IV). It was used in the synthesis of an asymmetrical tetradentate Schiff base via condensation with dehydroacetic acid and salicylic aldehyde.
