Description

Dicyclohexylphenol CAS NO 35406-29-2 is a high-purity, substituted phenolic compound valued for its role as a versatile chemical intermediate and performance additive. Its unique sterically hindered structure provides enhanced stability, making it a critical component in the synthesis of advanced materials. This product is essential for manufacturers in the polymer, specialty chemical, and lubricant industries seeking to improve product performance and thermal-oxidative resistance.

Application

• Polymer Stabilizer & Antioxidant: Acts as a key intermediate in the production of high-performance phenolic antioxidants for plastics (e.g., polyolefins) and elastomers to prevent thermal degradation.
• Lubricant & Fuel Additive Precursor: Used in synthesizing ashless anti-wear and antioxidant additives for engine oils, industrial lubricants, and aviation fuels.
• Specialty Chemical Synthesis: Serves as a building block for agrochemicals, pharmaceuticals, and UV absorbers due to its reactive phenolic hydroxyl group and bulky cyclohexyl substituents.
• Resin & Coating Modifier: Imparts improved flexibility, adhesion, and weathering resistance when incorporated into epoxy, phenolic, or alkyd resin systems.
• Metal Deactivator Intermediate: A precursor for compounds that chelate metal ions, preventing catalytic oxidation in industrial fluids and polymers.

Quality Control

Our Dicyclohexylphenol is manufactured under a strict quality management system. Every batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation (IR), to ensure it meets exacting specifications for industrial and fine chemical applications. Certificates of Analysis (COA) documenting all critical parameters are available upon request to 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). This material is easily oxidized and should be stored under an inert atmosphere (e.g., nitrogen) for long-term preservation. Keep away from strong oxidizing agents.
