2,4,6-Tri-tert-butylphenol (CAS 732-26-3) is a sterically hindered phenolic antioxidant widely used to stabilize rubber, plastics, fuels, and lubricants against oxidative degradation.
Its key selling points include excellent thermal stability, low volatility, and non-staining properties, making it ideal for light-colored polymers. It acts as an efficient free radical scavenger and serves as a crucial intermediate for synthesizing phosphite antioxidants like Irgafos 168.
Compliance Note: While effective, it is identified as a PBT (Persistent, Bioaccumulative, and Toxic) substance under various regulations (EU REACH, US TSCA). Ensure strict adherence to local environmental and safety guidelines when promoting this chemical grade.

Uses:
2,4,6-Tri-tert-butylphenol (CAS 732-26-3) is a sterically hindered phenolic antioxidant widely used as an industrial stabilizer for rubber, plastics, fuels and lubricants, and as a synthesis intermediate; its key selling points are strong antioxidant efficiency, low volatility, non-staining/non-discoloring performance, and broad compatibility, though it is a regulated PBT/SVHC substance requiring careful compliance handling.
What it is
Chemical name: 2,4,6-Tri-tert-butylphenol, also called 2,4,6-TTBP, Antioxidant 333, Antioxidant 246.
CAS No.: 732-26-3.
Molecular formula: C₁₈H₃₀O; MW 262.43.
Appearance: White to pale yellow crystalline powder.
Melting point: About 125–135 °C.
Solubility: Soluble in alcohols, esters, alkanes and aromatic hydrocarbons; insoluble in water.
Structure feature: Sterically hindered phenol; the phenolic hydroxyl group scavenges free radicals, while the three tert-butyl groups provide steric protection and thermal stability.
Main uses
Rubber antioxidant / anti-aging agent: Used in natural rubber and synthetic rubbers such as BR and SBR to delay oxidative aging.
Polymer stabilizer: Used as an antioxidant and heat stabilizer for polyolefins such as PE and PP, and for high-impact polystyrene; helps reduce yellowing and thermal degradation.
Fuel and lubricant additive: Added to gasoline, jet fuel, diesel, biodiesel and lubricating oils to inhibit oxidation, sludge formation, and rise in acid value or viscosity.
Resin, adhesive and coating stabilizer: Helps prevent yellowing and performance loss during storage and processing.
Chemical intermediate: Used to prepare phosphite antioxidants such as Antioxidant 633 and 641, and other hindered phenolic derivatives.
Other reported uses: It has been reported in some sources for food, cosmetic and pharmaceutical applications, but these uses are highly market- and regulation-dependent and should not be promoted without confirmed local compliance.
Selling points for chemical-grade promotion
Strong hindered-phenol antioxidant action: Efficiently scavenges free radicals and slows oxidative degradation in rubber, plastics and oils.
Good thermal stability and low volatility: Higher molecular weight than many simple phenolic antioxidants, giving lower volatility and better heat resistance in processing.
Non-staining and non-discoloring: Suitable for light-colored or transparent polymer systems where color stability matters.
Good oil and polymer compatibility: Dissolves well in common organic solvents and hydrocarbon systems, making formulation easier.
Synergistic compatibility: Can be combined with phosphite antioxidants and UV absorbers to improve overall stabilization.
Broad industrial application base: Covers rubber, plastics, fuels, lubricants, adhesives and chemical synthesis, supporting multi-industry customer targeting.
Compliance notes to mention to buyers
It has been identified as a PBT substance and listed under regulatory frameworks such as U.S. TSCA and EU REACH; it has also been identified as an SVHC candidate.
GHS hazard information includes risks such as harm if swallowed, potential skin sensitization, potential organ effects from prolonged exposure, and high toxicity to aquatic life with long-lasting effects.
For export or downstream cosmetic, food-contact, pharmaceutical or lubricant applications, customers should verify current local regulations, allowed use levels and SDS/REACH/TSCA status before promotion.
