Para Phenylenediamine Powder, Purity : 99% for Industrial

Para-Phenylenediamine (PPD) is an organic compound with the chemical formula C₆H₄(NH₂)₂. It is a derivative of aniline and appears as a white to slightly reddish crystalline powder, though it can darken upon exposure to air and light due to oxidation. PPD is primarily used in the manufacturing of dyes and pigments, particularly in hair dyes, where it serves as a precursor that reacts with hydrogen peroxide to produce a permanent color. Key Characteristics: Molecular Formula: C₆H₄(NH₂)₂ Molar Mass: 108.14 g/mol Appearance: White to slightly reddish crystalline powder. Solubility: Soluble in water, ethanol, and ether. Melting Point: 138-141°C (280-286°F) Uses: Hair Dyes: PPD is commonly used in hair dye formulations because it provides long-lasting color and is capable of producing various shades when combined with other chemicals. Textile Dyes: PPD is used in the production of azo dyes for fabrics. Rubber Chemicals: It is also utilized in the rubber industry as an antioxidant. Safety: PPD is known to cause allergic reactions, particularly in individuals with sensitive skin. It can cause dermatitis, eye irritation, and respiratory issues if inhaled. Handling PPD requires care, including the use of gloves and protective equipment.
