Description

General description

The photooxidation of 3,3′-diaminobenzidine by Chlamydomonas reinhardii and blue-green algae has been investigated.[1] Electropolymerization of 3,3′-diaminobenzidine on solid substrate electrode (Platinum, Gold and Glassy Electrode) affords stable and water insoluble films.

Application

Peroxidase substrate; reagent for spectrophotometric determination of selenium.

3,3′-Diaminobenzidine, a dark brown dye, was used as an antibody-specific stain to identify the paired antibodies in breast tissue.[2] 3,3′-Diaminobenzidine may be used for the determination of selenium and for the synthesis of a useful, linear, Schiff-base coordination polymer.
