Application | 3,3 '-diaminobenzidine (DAB) is widely used in chemistry, biochemistry, materials and other research areas. DAB has been focused on research and used as a monomer for the preparation of high-grade polymer materials, mainly for the synthesis of heat-resistant polymer resins and synthetic fibers, however, its application in the field of analytical chemistry as a chromogenic agent is only found in the spectrophotometric determination of selenium. |
