Description

2,6-Di-tert-Butyl-4-Methoxyphenol is a high-performance synthetic phenolic antioxidant widely recognized for its efficacy in stabilizing organic materials against oxidative degradation. Its primary value lies in its ability to interrupt free-radical chain reactions, thereby significantly extending the shelf life and maintaining the integrity of sensitive formulations. This compound is essential for manufacturers in the polymer, food, and cosmetic industries who require reliable protection against rancidity, discoloration, and loss of mechanical properties. The product is supplied with a guaranteed specification to ensure batch-to-batch consistency for critical industrial applications.

Application

• Polymer & Plastics Stabilizer: Used as an antioxidant in the production and processing of polyolefins (e.g., polyethylene, polypropylene), synthetic rubbers, and adhesives to prevent thermal and oxidative degradation during extrusion and molding.
• Food & Feed Additive: Functions as a preservative (antioxidant) in fats, oils, and fat-containing food products to prevent rancidity and extend shelf life, often used where BHT or BHA analogs are applicable.
• Cosmetic & Personal Care: Incorporated into creams, lotions, and lipsticks to stabilize the lipid components and prevent oxidation, thereby protecting product quality and fragrance.
• Industrial Fluids & Lubricants: Added to transformer oils, turbine oils, and synthetic lubricants to inhibit oxidation and sludge formation, enhancing operational longevity and performance.
• Fuel & Petrochemical Additive: Serves as an antioxidant in gasoline, jet fuels, and other hydrocarbon streams to improve storage stability and prevent gum formation.
• Pharmaceutical Intermediate: Employed in the synthesis of other complex antioxidant molecules or as a stabilizing agent in certain pharmaceutical formulations.

Quality Control

Our 2,6-Di-tert-Butyl-4-Methoxyphenol is manufactured under a strict quality management system. Every batch is subjected to rigorous analytical testing, including assay, identification, and impurity profiling, to ensure it meets the required specifications for industrial, food-grade, or technical applications. A comprehensive Certificate of Analysis (COA) detailing purity, physical characteristics, and test results is provided with each shipment to guarantee traceability and compliance.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Keep away from heat, sparks, and open flame. Due to its nature as an easily oxidized compound, prolonged storage under an inert atmosphere (e.g., nitrogen) is recommended for optimal long-term stability.
