Description

4-[1-Ethyl-1-(4-Hydroxy-3,5-Dimethylphenyl)Propyl]-2,6-Dimethylphenol is a high-purity, hindered phenolic compound valued for its role as an effective antioxidant and stabilizer. This chemical is critical for protecting materials from oxidative degradation, thereby extending product shelf life and maintaining performance integrity. It is primarily needed by manufacturers in the polymer, rubber, and specialty chemical industries seeking reliable additive solutions.

Application

• Primary antioxidant in polymer production (e.g., polyolefins, PVC, engineering plastics) to prevent thermal and oxidative degradation during processing and end-use.
• Stabilizer component in synthetic rubber and elastomers to enhance durability and resist aging.
• Additive in lubricants, greases, and hydraulic fluids to inhibit oxidation and sludge formation.
• Intermediate in the synthesis of more complex phenolic antioxidants and specialty chemicals.
• Stabilizing agent for adhesives, sealants, and coatings to improve weatherability and longevity.
• Potential use as a preservative in select industrial formulations where phenolic antioxidants are applicable.

Quality Control

Our 4-[1-Ethyl-1-(4-Hydroxy-3,5-Dimethylphenyl)Propyl]-2,6-Dimethylphenol is produced under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure it meets precise specifications for identity, purity, and performance. Certificates of Analysis (COA) documenting these results are available upon request to support your quality assurance and regulatory compliance needs.

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 light-sensitive nature, containers should be kept in the original packaging or opaque containers until use.
