Description

4,4'-[(2,4,6-Trihydroxy-5-Butyryl-1,3-Phenylene)Bis(2-Methylpropane-1,1-Diyl)]Bis(5-Hydroxy-2,2,6,6-Tetramethyl-4-Cyclohexene-1,3-Dione) is a high-purity, complex organic compound belonging to the class of hindered phenolic diketones. This specialty chemical is valued for its role as a high-performance stabilizer and antioxidant in demanding polymer systems. It is primarily sought by manufacturers in the plastics, coatings, and specialty chemical synthesis industries who require advanced protection against thermal and oxidative degradation.

Application

• Polymer Stabilizer: Acts as a highly effective antioxidant and light stabilizer in engineering plastics, polyolefins (e.g., PP, PE), and synthetic rubbers to extend service life.
• Additive for High-Performance Coatings: Incorporated into automotive, industrial, and protective coatings to prevent yellowing, cracking, and loss of gloss due to heat and UV exposure.
• Synthetic Intermediate: Serves as a key building block in the multi-step synthesis of more complex hindered amine light stabilizers (HALS) and other specialty additives.
• Adhesive & Sealant Formulations: Enhances the long-term thermal stability and durability of hot-melt adhesives and elastomeric sealants.
• Lubricant & Fuel Additive: Used as an antioxidant component in synthetic lubricants and industrial fluids to inhibit oxidation and sludge formation.
• Research & Development: Utilized in academic and industrial R&D for studying novel stabilization mechanisms and developing next-generation polymer additives.

Quality Control

Our production of 4,4'-[(2,4,6-Trihydroxy-5-Butyryl-1,3-Phenylene)Bis(2-Methylpropane-1,1-Diyl)]Bis(5-Hydroxy-2,2,6,6-Tetramethyl-4-Cyclohexene-1,3-Dione) adheres to a rigorous quality management system. Every batch is analyzed using advanced techniques like HPLC, GC, and NMR to ensure identity, purity, and consistency. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with each shipment 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 a controlled room temperature (15-25°C). Due to its sensitivity to oxidation, it is recommended to store under an inert atmosphere (e.g., nitrogen) for long-term preservation. Keep away from heat sources and incompatible materials.
