4-tert-octylphenol

4-tert-Octylphenol (CAS 140-66-9), also known as 4-(1,1,3,3-tetramethylbutyl)phenol, is an alkylphenol intermediate used across industrial synthesis and formulation chemistry. It functions primarily as a building block for nonionic surfactants and phenolic resins.

The chemical is also essential for antioxidant systems. In coatings and adhesives, it serves as a reactive intermediate in the production of alkylphenol-ethoxylate surfactants and tackifying resins that influence adhesion and film formation.

Lubricant and metalworking formulators incorporate it into antioxidant and extreme-pressure additive packages to extend fluid service life. This ensures high performance in demanding industrial environments and mechanical systems.

In plastics and polymer processing, it contributes to UV stabilizer and antioxidant formulations. These protect against thermal and photo-oxidative degradation during compounding, maintaining the structural integrity of the final plastic products.

Printing ink manufacturers use it as a resin modifier to adjust viscosity, adhesion, and drying performance in solvent-based systems. This versatility makes it a staple component in high-quality industrial printing applications.

4-tert-Octylphenol is supplied as a white to off-white solid in flake or molten liquid form, depending on logistics requirements. Technical grade is the standard commercial offering, with purity specifications typically at 99% or above.

Packaging options generally include drums and bulk containers suited to industrial procurement volumes. Our logistics team ensures that all shipments meet the necessary safety and handling requirements for chemical distribution.
