Tributylphenol

Tributylphenol (CAS 28471-16-1), commercially recognized as 2,4,6-Tributylphenol, is a hindered phenolic compound used across plastics, rubber, and energy sectors as an antioxidant stabilizer.

Its bulky alkyl substitution pattern makes it effective at inhibiting oxidative degradation in demanding industrial formulations, acting as a plasticizer and process solvent for various applications.

In plastics and polymer processing, it functions as a stabilizer that protects resins and compounded materials from thermal oxidation during high-temperature manufacturing and extrusion processes.

Rubber and tire formulators incorporate it to extend service life by suppressing oxidative breakdown in vulcanized compounds, ensuring durability and performance in harsh environmental conditions.

In oil and gas applications, it is used as an additive in lubricants, process oils, and drilling fluids where oxidative stability under elevated temperatures is a primary formulation requirement.

It also serves as a carrier solvent in specialty industrial formulations where compatibility with hydrocarbon-based systems is a key selection criterion for chemical manufacturers and blenders.

Tributylphenol is supplied as a liquid at ambient conditions, with bulk and drummed packaging available for industrial procurement. Technical grade is the standard commercial offering.

Buyers should confirm purity specifications and isomeric profile when evaluating supplier documentation for formulation-critical applications to ensure the highest performance in their final products.
