Description

2,2,4-Trimethyl-7-(1,1,3,3-Tetramethylbutyl)Chroman-6-Ol is a hindered phenolic antioxidant belonging to the chroman chemical class. This compound is valued for its ability to inhibit oxidative degradation in various organic matrices, thereby extending product shelf life and maintaining performance integrity. It is primarily sought by manufacturers in the polymer, rubber, lubricant, and specialty chemical industries seeking to protect their formulations from thermal and oxidative stress.

Application

• Polymer Stabilization: Acts as a highly effective antioxidant in polyolefins (e.g., PP, PE), polyurethanes, and synthetic rubbers to prevent chain scission and discoloration during processing and end-use.
• Lubricant & Fuel Additive: Used in engine oils, industrial lubricants, and fuels to control oxidation, reduce sludge formation, and extend operational life.
• Adhesive & Sealant Formulations: Enhances the durability and thermal stability of hot-melt adhesives, sealants, and caulking compounds.
• Coating & Resin Protection: Incorporated into paints, varnishes, and unsaturated polyester resins to prevent yellowing and maintain film properties.
• Elastomer Manufacturing: Protects synthetic elastomers like SBR, NBR, and EPDM from oxidative aging, preserving elasticity and mechanical strength.
• Fat & Oil Stabilization: Employed as an antioxidant in technical-grade fats, oils, and waxes to prevent rancidity.

Quality Control

Our production of 2,2,4-Trimethyl-7-(1,1,3,3-Tetramethylbutyl)Chroman-6-Ol adheres to a stringent quality management system. Every batch undergoes rigorous analytical testing, including HPLC for assay and purity, to ensure compliance with agreed specifications and industry standards. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and physical parameters is provided with each shipment to guarantee traceability and product consistency for our global B2B clients.

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; prolonged storage under an inert atmosphere (e.g., nitrogen) is recommended for optimal long-term stability. Keep away from strong oxidizing agents.
