Description

2(3H)-Furanone, 3-[[3,5-Bis(1,1-Dimethylethyl)-4-Hydroxyphenyl]Methylene]Dihydro-, (E)- is a specialized hindered phenolic compound, a derivative of butylated hydroxytoluene (BHT). This product matters as a high-performance antioxidant and stabilizer intermediate, designed to inhibit oxidative degradation in sensitive formulations. It is needed by manufacturers in the polymer, lubricant, and specialty chemical industries seeking to enhance the longevity and stability of their products under demanding conditions.

Application

• Polymer Stabilization: Acts as a key intermediate in the synthesis of advanced phenolic antioxidants for plastics (e.g., polyolefins like PP, PE) and synthetic rubbers to prevent thermal and oxidative degradation.
• Lubricant & Fuel Additives: Used in formulating antioxidant packages for engine oils, industrial lubricants, and fuels to extend service life and maintain performance.
• Specialty Chemical Synthesis: Serves as a crucial building block for creating custom stabilizers, UV absorbers, and other functional additives.
• Adhesive & Sealant Formulations: Incorporated to improve the aging resistance and shelf-life of high-performance adhesives and sealants.
• Coating Resins: Enhances the durability of industrial and protective coatings by preventing resin degradation from heat and oxidation.
