Description

4,4'-[Ethylenebis(Oxy)]Bis[n-(1,3-Dimethylbutyl)Aniline] is a specialized aromatic amine derivative, primarily valued as a high-performance antioxidant and antiozonant intermediate in polymer science. Its chemical structure provides excellent protection against thermal degradation and oxidative stress, extending the service life of critical materials. This compound is essential for manufacturers in the rubber, elastomer, and specialty polymer industries seeking to enhance product durability and performance under demanding conditions.

Application

• Primary intermediate for the synthesis of p-phenylenediamine (PPD) based antiozonants used in tire sidewalls and other rubber components.
• Key antioxidant additive in the production of high-performance elastomers such as nitrile rubber (NBR), ethylene-propylene-diene monomer (EPDM), and polychloroprene.
• Stabilizer for polyurethane (PU) systems and other specialty polymers susceptible to thermal-oxidative degradation.
• Used in the formulation of industrial rubber goods including hoses, belts, seals, and gaskets to prevent cracking and aging.
• Component in lubricant and fuel additive packages to inhibit oxidation and sludge formation.
• Research and development of novel polymer stabilizers and functional materials.

Quality Control

Our production of 4,4'-[Ethylenebis(Oxy)]Bis[n-(1,3-Dimethylbutyl)Aniline] adheres to stringent quality management protocols to ensure batch-to-batch consistency and high purity. The material is characterized using advanced analytical techniques including HPLC, GC, and NMR spectroscopy. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are provided with every shipment to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after initial opening to prevent moisture absorption, which can affect product stability and performance. Keep away from strong oxidizing agents.
