Description

2,4-Di-tert-Butylphenol is a high-purity, hindered phenolic compound widely used as a versatile chemical intermediate and antioxidant precursor. Its sterically hindered structure provides excellent stability, making it a critical building block for advanced polymer stabilizers and specialty chemicals. This product is essential for manufacturers in the plastics, lubricant, and agrochemical industries seeking to enhance the performance and longevity of their formulations.

Application

• Antioxidant Synthesis: A key intermediate in the production of high-performance phenolic antioxidants (e.g., Irganox® 1076, Irgafos® 168 analogs) for plastics and polymers.
• Polymer Stabilizers: Used to manufacture light and heat stabilizers that protect polyolefins (PP, PE), PVC, and engineering plastics from oxidative degradation.
• Lubricant & Fuel Additives: Serves as a precursor for additives that prevent oxidation and sludge formation in industrial lubricants, greases, and fuels.
• Agrochemical Intermediates: Employed in the synthesis of certain pesticides, herbicides, and plant growth regulators.
• UV Absorber Production: A building block for benzotriazole and other classes of ultraviolet light absorbers used in coatings and plastics.
• Resin & Adhesive Modifiers: Imparts improved aging resistance and stability to phenolic resins, epoxy hardeners, and adhesive systems.
• Chemical Intermediate: Used in various organic synthesis processes for pharmaceuticals, dyes, and other fine chemicals.

Quality Control

Our 2,4-Di-tert-Butylphenol is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing, including GC/HPLC for assay and purity, to ensure it meets precise specifications for use in sensitive applications like polymer stabilization. Certificates of Analysis (COA) documenting purity, identity, and impurity profiles are available for each lot upon request, ensuring full traceability and compliance with your quality standards.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is easily oxidized; for long-term storage or after opening, storing under an inert atmosphere (e.g., nitrogen) is recommended to maintain optimal purity. Keep away from strong oxidizing agents.
