Octadecyl 3-(3,5-Di-tert-butyl-4-hydroxyphenyl)propionate(CAT: R034427) is a sterically hindered phenolic antioxidant commonly used to stabilize polymers and prevent oxidative degradation. The molecule combines a bulky, lipid-compatible octadecyl chain with a highly effective hindered phenol moiety, enhancing both thermal stability and lipid solubility. This dual functionality makes it ideal for protecting polyolefins, synthetic rubbers, and lubricants against heat and oxygen-induced deterioration. The compound’s long alkyl chain ensures excellent compatibility with hydrophobic matrices, reducing volatility and migration. Its antioxidant properties are widely exploited in materials science, packaging, and industrial applications where prolonged polymer durability and resistance to free-radical oxidation are critical.
