CAS 15452-89-8: 2,2′-Sulfonylbis[4-(1,1,3,3-tetramethylbutyl)phenol]

Description: 2,2′-Sulfonylbis[4-(1,1,3,3-tetramethylbutyl)phenol], with CAS number 15452-89-8, is a chemical compound primarily used as an antioxidant in various industrial applications, particularly in plastics and rubber. This substance features a sulfonyl group that connects two phenolic moieties, each substituted with bulky tetramethylbutyl groups, which enhance its thermal stability and solubility in non-polar solvents. The presence of these bulky groups also contributes to its effectiveness in preventing oxidative degradation of materials. Typically, it appears as a solid at room temperature and is characterized by its high melting point. The compound is known for its low volatility and resistance to heat, making it suitable for high-temperature applications. Additionally, it exhibits good compatibility with a variety of polymers, which is essential for its role as an additive. Safety data indicates that, while it is generally considered to have low toxicity, appropriate handling and safety measures should be observed to minimize exposure during industrial use.
