4,4′-Isopropylidene-bis(2-t-butylphenol)（Cat No.:M016762） is a chemical compound featuring two 2-t-butylphenol groups linked through a central isopropylidene bridge. This molecular structure imparts significant antioxidant properties, making it widely utilized as a stabilizer in plastics and rubber manufacturing to prevent oxidation and degradation of materials. The bulky t-butyl groups enhance their effectiveness by providing steric hindrance that protects the phenolic hydroxyl groups, crucial for scavenging free radicals. Such a configuration makes it highly effective in environments exposed to heat and oxygen, thereby extending the life and maintaining the integrity of polymer-based products.
