Thermo Scientific™ O-Phenylenediamine (OPD) is a high-purity organic compound primarily used as an intermediate in dye, pigment, polymer, and pharmaceutical manufacturing. With a purity of 98%, this compound ensures reliable performance in synthetic and analytical workflows, especially in oxidation-reduction reactions, enzyme substrate systems, and fluorescence detection in biochemistry and immunohistochemistry.
O-Phenylenediamine is a colorless to pale yellow crystalline solid that darkens upon exposure to air and light. It is known for its strong reducing properties and is often used in peroxidase-based assays due to its chromogenic reaction with hydrogen peroxide.
