CAS 128-39-2 2.6-Di-tert-butylphenol
Overview
2.6-Di-tert-butylphenol (2,6-DTBP; CAS 128-39-2; C₁₄H₂₂O, 206.32 g/mol) is a hindered phenolic antioxidant/radical scavenger used to inhibit peroxide/gum formation and oxidative color/viscosity rise in fuels (gasoline/jet/diesel), lubricants & greases, and as a stabilizer for polymers, elastomers, adhesives, and resins.
Product Description
128-39-2 2,6-Di-tert-butylphenol
Supplied as a white to off-white, low-melting crystalline solid (may soften near ambient), it is readily soluble in common organic solvents (aromatics, aliphatics, ethers, alcohols) and insoluble in water, making it easy to post-add or pre-dissolve for blending. Typical treat levels are system-dependent (from ppm in fuels to ≤1% in lubricant/polymer systems). Handle as an irritant and aquatic-hazard material; avoid strong oxidizers and high heat; store tightly closed, cool and dry. COA/TDS/SDS available; lab-to-bulk packaging on request.
