Description

Isobutrin CAS NO 536-01-6 is a high-purity chemical intermediate, also known as 2,6-Di-tert-butyl-4-methylphenol (BHT), a synthetic phenolic antioxidant. It is valued for its ability to inhibit oxidation and extend the shelf life of a wide range of industrial and consumer products by scavenging free radicals. This compound is essential for manufacturers in the polymer, fuel, food, and cosmetics industries seeking reliable and effective stabilization solutions.

Application

• Polymer & Rubber Stabilizer: A primary antioxidant used to prevent thermal and oxidative degradation in polyethylene, polypropylene, polystyrene, and synthetic rubbers during processing and in-service.
• Fuel & Lubricant Additive: Inhibits gum formation and oxidation in gasoline, jet fuels, and industrial lubricants, improving performance and storage stability.
• Food Preservative (where compliant): Used as an antioxidant (E321) to prevent rancidity in fats, oils, and fat-containing foods, as well as in food packaging materials.
• Cosmetics & Personal Care: Protects oils, waxes, and other ingredients in creams, lipsticks, and lotions from oxidative spoilage.
• Pharmaceutical Excipient: Serves as an antioxidant in certain pharmaceutical formulations and packaging to maintain product integrity.
• Industrial Fluids: Stabilizes transformer oils, hydraulic fluids, and other specialty industrial fluids against oxidative breakdown.
