Description

4-tert-Butyl-2,6-Xylenol CAS NO 879-97-0 is a sterically hindered phenolic compound widely valued as a high-performance antioxidant and stabilizer. Its molecular structure provides excellent protection against oxidative degradation in various organic matrices. This chemical is essential for manufacturers in the polymer, fuel, and specialty chemical industries seeking to enhance product longevity and performance under demanding conditions.

Application

• Polymer Stabilizer: Acts as a primary antioxidant in polyolefins (e.g., polyethylene, polypropylene), synthetic rubbers, and adhesives to prevent thermal and oxidative degradation during processing and service life.
• Fuel and Lubricant Additive: Inhibits gum formation and oxidation in gasoline, jet fuels, and industrial lubricants, improving stability and shelf life.
• Chemical Intermediate: Serves as a key building block in the synthesis of more complex antioxidants, UV stabilizers, and other specialty chemicals.
• Industrial Antioxidant: Used in transformer oils, hydraulic fluids, and other industrial fluids to protect against oxidative breakdown.
• Preservative: Finds application in select industrial formulations where oxidative spoilage is a concern.
