Description

Sodium 2,4-Di-tert-Butylphenolate is a sterically hindered phenolic salt widely utilized as a high-performance intermediate and stabilizer in advanced chemical synthesis. This compound matters for its role in protecting materials from oxidative and thermal degradation, thereby extending product lifespan and performance. It is primarily needed by manufacturers in the polymer, lubricant, and specialty chemical industries seeking to enhance the stability of their formulations.

Application

• Primary intermediate in the synthesis of high-performance hindered phenol antioxidants (e.g., Irganox 1076, Irgafos 168 precursors).
• Key component in polymer stabilization packages for polyolefins (PP, PE), engineering plastics, and synthetic rubbers to prevent thermal-oxidative degradation.
• Stabilizer and acid scavenger in industrial lubricants and greases, improving their thermal stability and service life.
• Used in the production of specialty chemicals such as UV stabilizers, light absorbers, and other additive blends.
• Acts as a catalyst or co-catalyst in select organic synthesis reactions requiring a hindered phenolate base.
• Potential use as a stabilizer in adhesives, sealants, and coatings to prevent premature aging and maintain properties.

Quality Control

Our Sodium 2,4-Di-tert-Butylphenolate is manufactured under a stringent quality management system. Each batch undergoes rigorous analytical testing to ensure it meets precise specifications for purity, identity, and performance. Certificates of Analysis (COA) documenting key parameters such as assay, moisture content, and related substances 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, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed to minimize exposure to atmospheric moisture. Keep away from strong acids and oxidizing agents.
