CAS 3294-03-9: 2,2′-Thiobis[4-(1,1,3,3-tetramethylbutyl)phenol]

Description: 2,2′-Thiobis[4-(1,1,3,3-tetramethylbutyl)phenol], commonly known as a phenolic antioxidant, is a chemical compound characterized by its dual phenolic structure linked by a sulfur atom. This compound is primarily used in various industrial applications, particularly as an antioxidant in plastics, rubber, and other materials to prevent oxidative degradation. It exhibits excellent thermal stability and resistance to oxidation, making it effective in prolonging the lifespan of products exposed to heat and light. The bulky tetramethylbutyl groups enhance its solubility in non-polar solvents and contribute to its steric hindrance, which helps in stabilizing the phenolic structure. Additionally, this compound is known for its low volatility and high molecular weight, which further aids in its performance as an antioxidant. Safety data indicates that while it is generally considered safe for use in industrial applications, appropriate handling and safety measures should be observed to minimize exposure. Overall, its unique structure and properties make it a valuable additive in various formulations.
