1,2-Bis[4-(1,1-dimethylethyl)phenyl]-2-hydroxyethanone

Description:
1,2-Bis[4-(1,1-dimethylethyl)phenyl]-2-hydroxyethanone, commonly known as a type of hindered phenol antioxidant, is characterized by its complex molecular structure that includes two bulky tert-butyl groups attached to phenolic rings and a hydroxyethanone moiety. This compound is typically a solid at room temperature and exhibits good thermal stability, making it effective in preventing oxidative degradation in various materials, particularly polymers. Its antioxidant properties stem from the ability to donate hydrogen atoms to free radicals, thus stabilizing them and preventing further reactions that could lead to material degradation. The presence of the hydroxy group enhances its reactivity and solubility in organic solvents. Additionally, this compound is often used in industrial applications, including plastics, rubber, and coatings, due to its effectiveness in prolonging the lifespan of these materials. Safety data should be consulted for handling and exposure guidelines, as with any chemical substance.
