p-Phenylenediamine PDA CAS 106-50-3 | Chemical Intermediate | Bulk Supply

Basic Information and Chemical Properties

p-Phenylenediamine CAS 106-50-3, also known as PDA or 1,4-Phenylenediamine, is an aromatic diamine chemical intermediate widely used in dye intermediate production, polymer material research, analytical applications, and industrial formulation projects. Its molecular formula is C6H8N2, with a molecular weight of approximately 108.14 g/mol. The product is commonly supplied as white to light brown, grey, or purple crystalline solid, and it may darken gradually when exposed to air or light due to oxidation. PDA has good reactivity as an aromatic amine, and final specifications should be confirmed by COA, assay, appearance, moisture, and impurity testing. Recommended storage conditions are sealed, cool, dry, protected from light, and away from strong oxidizing agents.
