Description

2-Amino-4,6-Di-tert-Butylphenol is a sterically hindered phenolic amine, a versatile chemical intermediate prized for its antioxidant and metal-chelating properties. Its molecular structure makes it highly effective as a stabilizer and inhibitor in polymer and fuel systems, preventing degradation from heat and oxidation. This compound is essential for manufacturers in the polymer, lubricant, and specialty chemical industries seeking to enhance product longevity and performance.

Application

• Polymer Stabilizer: Acts as a highly effective antioxidant and metal deactivator in polyolefins (e.g., polyethylene, polypropylene) and other polymers to prevent thermal and oxidative degradation during processing and service life.
• Fuel & Lubricant Additive: Used as an antioxidant and stabilizer in gasoline, diesel, and synthetic lubricants to inhibit gum formation, viscosity increase, and acid generation.
• Chemical Intermediate: Serves as a key building block for synthesizing more complex hindered amine light stabilizers (HALS) and other specialty antioxidants.
• Rubber Industry: Employed as an antiozonant and antioxidant in the production of synthetic rubbers and elastomers to prevent cracking and aging.
• Metal Chelation: Functions as a ligand or chelating agent in catalytic systems and for metal ion sequestration in various industrial processes.
• Research & Development: Utilized in academic and industrial R&D for studying antioxidant mechanisms and developing new stabilization technologies.

Quality Control

Our 2-Amino-4,6-Di-tert-Butylphenol is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing to ensure it meets precise specifications for purity, identity, and performance. A comprehensive Certificate of Analysis (COA) detailing assay, impurity profile, and physical properties is provided with each shipment to guarantee consistency and traceability for 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.
