Description

o-Pentylphenol CAS NO 136-81-2 is a versatile alkylphenol derivative widely used as a key chemical intermediate in industrial synthesis. Its value lies in its ability to act as a building block for more complex molecules, particularly in the production of specialized polymers, resins, and surfactants. This product is essential for manufacturers in the polymer, agrochemical, and specialty chemical industries seeking reliable intermediates for their production processes.

Application

• Chemical Intermediate: A crucial precursor in the synthesis of phenolic resins, epoxy resins, and other high-performance polymers.
• Surfactant & Detergent Manufacturing: Used in the production of alkylphenol ethoxylates (APEs), which serve as nonionic surfactants in industrial and institutional cleaning formulations.
• Agrochemical Synthesis: Serves as an intermediate in the manufacture of certain pesticides, herbicides, and plant growth regulators.
• Lubricant & Fuel Additive: Employed in the formulation of antioxidant and anti-wear additives for lubricating oils and fuels.
• Rubber & Plastic Antioxidant: Acts as a starting material for antioxidants that prevent degradation in rubber and plastic products.
• Pharmaceutical Intermediate: Used in specific synthetic pathways for active pharmaceutical ingredients (APIs) and other fine chemicals.
