Description:
o-Dianisidine is a peroxidase substrate and used as a redox indicator dye. Redox indicators are colorimetric reagents which provide a characteristic color change at a specific electrode potential. o-Dianisidine has been has been used for neutrophil myeloperoxidase activity (MPO) assay or measurment of glucose-oxidase or caeruloplasmin oxidase. It is used as an intermediate for the preparation of azo dyes, pigments and o-dianisidine diisocyanate, which finds application in adhesives, polyurethane elastomers and resins. It is also used in various industries like leather, paper, plastics, rubber and textiles. It acts as a reagent to detect metals, thiocyanates and nitrites. It is incompatible with strong oxidizing agents.
