Thermo Scientific™ p-Phenylenediamine (PPD) is a high-quality aromatic diamine with 97% purity, suitable for use in the synthesis of dyes, hair colorants, polymers, rubber antioxidants, and analytical chemistry applications. This compound appears as a white to gray crystalline solid that oxidizes rapidly in air, making it a powerful reducing agent in various redox reactions.
It is widely used as a key intermediate in industrial and research formulations, particularly where para-isomeric diamines are required. Due to its toxic and irritant nature, it must be handled with proper safety precautions in well-ventilated environments.
