2,6-di-tert-butyl-4-Heptylphenol丨CAS 765956-84-1

2,6-Di-tert-butyl-4-heptylphenol (CAS 765956-84-1) is widely used as an antioxidant and stabilizer in a range of industrial and chemical formulations. It functions effectively in polymers, lubricants, fuels, and oils to prevent oxidative degradation, which can cause discoloration, viscosity increase, and performance loss. In polymer processing, it protects materials such as polyethylene, polypropylene, and synthetic rubbers from heat and oxygen damage during manufacturing and long-term use. In lubricants and fuels, it helps maintain efficiency by inhibiting oxidation and sludge formation. It is also utilized in coatings, adhesives, and elastomer compounds where long-term thermal stability is crucial.

The compound's structure-featuring sterically hindered phenolic groups-provides exceptional antioxidant performance by efficiently scavenging free radicals and interrupting oxidative chain reactions. Its heptyl side chain enhances solubility in nonpolar matrices, improving compatibility with organic materials and hydrocarbon-based systems. 2,6-Di-tert-butyl-4-heptylphenol offers superior thermal and oxidative stability even under extreme processing conditions, extending product lifespan and preserving mechanical and color properties. Additionally, it performs effectively at low concentrations, reducing the need for excess additives.
