Product Information

• Name: 1,4-Phenylenediamine
• Synonyms: 1,4-Benzenediaminep-Phenylenediamine(4-Aminophenyl)amine
• Brand: Biosynth
• Description: Phenylenediamine is a heterocyclic amine that is used as a precursor to the dye intermediate 4-aminophenol. It has been shown to have high intramolecular hydrogen bonding and low intermolecular hydrogen bonding. Phenylenediamine has a redox potential of -1.8 V, which means it can be reduced by chemical reduction or electrolysis. The nitrogen atoms in phenylenediamine are able to form redox reactions with p-hydroxybenzoic acid, which is found in human serum, leading to the formation of quinoneimines and reactive oxygen species such as superoxide anion and hydroxyl radicals. These reactive oxygen species can cause toxicity in humans. Titration calorimetry studies show that phenylenediamine binds with water molecules at its ortho position, forming a hydrogen bond with the water molecule's OH group. This interaction may contribute to its toxic effects on living organisms.
