Description

p-(Ethylamino)Diphenylamine is a high-purity aromatic amine derivative, valued for its role as a versatile chemical intermediate and antioxidant precursor. Its chemical structure makes it particularly effective in applications requiring controlled oxidation inhibition and polymer stabilization. This product is essential for manufacturers in the rubber, polymer, and specialty chemical industries seeking reliable performance in demanding formulations.

Application

• Rubber Antioxidant/Antiozonant Intermediate: A key building block in the synthesis of p-phenylenediamine (PPD) and other amine-based antioxidants used to protect tires and industrial rubber goods from degradation.
• Polymer Stabilizer: Functions as a precursor for stabilizers that prevent thermal and oxidative degradation in plastics and synthetic fibers, extending product lifespan.
• Lubricant Additive Precursor: Used in the manufacture of ashless antioxidants and anti-wear agents for high-performance engine oils and industrial lubricants.
• Dye and Pigment Intermediate: Serves as a starting material in the synthesis of certain azo dyes and organic pigments, contributing to color fastness.
• Pharmaceutical Intermediate: Employed in controlled synthesis routes for specific active pharmaceutical ingredients (APIs) requiring its amine functionality.
• Research & Development: Utilized in academic and industrial R&D for studying antioxidant mechanisms and developing new stabilization systems.

Quality Control

Our p-(Ethylamino)Diphenylamine is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing, including assay, impurity profiling, and identity confirmation, to ensure it meets precise customer specifications and industry standards. A Certificate of Analysis (COA) detailing all test results is provided with every shipment to guarantee traceability and consistency.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Due to its easily oxidized nature, it is recommended to store under an inert atmosphere (e.g., nitrogen) for long-term preservation. Keep away from strong oxidizing agents, acids, and heat sources.
