p-Phenylenediamine PDA CAS 106-50-3 | Chemical Intermediate from China Suppliers and Factory for Bulk Supply

Basic Information and Chemical Properties

p-Phenylenediamine (CAS 106-50-3), commonly referred to as PDA or 1,4-Phenylenediamine, is an essential aromatic diamine chemical intermediate. This compound plays a pivotal role in the production of dye intermediates, polymer material research, analytical applications, and various industrial formulation projects. With a molecular formula of C6H8N2 and a molecular weight of approximately 108.14 g/mol, it is typically supplied as a crystalline solid ranging from white to light brown, grey, or purple. It is important to note that PDA may gradually darken when exposed to air or light due to oxidation. As a reactive aromatic amine, its final specifications should be verified through COA, assay, appearance, moisture, and impurity tests. For optimal preservation, this product must be stored in a sealed, cool, dry environment, away from light and strong oxidizing agents. As a leading manufacturer and supplier in China, our factory ensures the highest quality standards for p-Phenylenediamine to meet your industrial needs.
