Description

4,6-Bis(1-Phenylethyl)-o-Cresol is a sterically hindered phenolic compound, a class of chemicals valued for their antioxidant properties. This compound matters for its ability to inhibit oxidative degradation, thereby extending the functional lifespan of sensitive materials. It is needed by formulators and manufacturers in the polymer, rubber, and specialty lubricant industries seeking to enhance product stability and performance under demanding conditions.

Application

• Primary antioxidant and stabilizer in polymer and synthetic rubber production.
• Additive in lubricating oils and greases to prevent oxidation and sludge formation.
• Stabilizing agent in adhesives, sealants, and elastomers to improve heat aging resistance.
• Intermediate in the synthesis of more complex hindered phenol antioxidants and specialty chemicals.
• Protective additive in fuel and hydrocarbon-based systems to enhance oxidative stability.
• Potential use as a stabilizer in polyolefins such as polyethylene and polypropylene.

Quality Control

Our 4,6-Bis(1-Phenylethyl)-o-Cresol is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing to ensure it meets precise specifications for identity, purity, and performance. A comprehensive Certificate of Analysis (COA) detailing assay, impurity profile, and physical properties is provided with each shipment to guarantee consistency and support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, 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, especially after opening the original container. Keep away from heat, sparks, and open flame.
