Description

4-sec-Butyl-2-tert-Butylphenol is a sterically hindered phenolic compound, a member of the alkylphenol family. This chemical is valued for its role as a versatile intermediate and antioxidant precursor in industrial synthesis. It is primarily needed by manufacturers in the polymer, lubricant, and specialty chemical industries seeking to enhance product stability and performance.

Application

• Antioxidant Intermediate: A key building block in the synthesis of high-performance phenolic antioxidants for plastics and rubber.
• Polymer Stabilizer: Used to produce additives that protect polymers like polyolefins from thermal and oxidative degradation during processing and service life.
• Lubricant Additive Precursor: Employed in formulating antioxidant components for engine oils and industrial lubricants to prevent sludge formation and viscosity increase.
• Chemical Synthesis: Serves as an intermediate in organic synthesis for agrochemicals, dyes, and other specialty chemicals.
• Fuel Additive Component: Used in the development of stabilizers that inhibit gum formation in gasoline and other fuels.
• Resin Modifier: Acts as a modifier in phenolic and other resin systems to alter properties or introduce functional groups.

Quality Control

Our 4-sec-Butyl-2-tert-Butylphenol is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure it meets precise specifications for purity and consistency. Certificates of Analysis (COA) documenting key parameters are available upon request to support your quality assurance protocols.

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, maintaining an inert atmosphere (e.g., under nitrogen) is recommended to preserve quality. Keep away from strong oxidizing agents.
