4,4'-(ethene-1,2-diyl)bis(2,6-di-tert-butylcyclohexa-2,4-dien-1-one); CAS No.: 809-73-4; 4,4'-(ethene-1,2-diyl)bis(2,6-di-tert-butylcyclohexa-2,4-dien-1-one). PROPERTIES: 4,4'-(ethene-1,2-diyl)bis(2,6-di-tert-butylcyclohexa-2,4-dien-1-one) appears as a white to off-white crystalline powder with a slight odor. Its molecular formula is C28H36O4, corresponding to a molecular weight of approximately 440.6 g/mol. The compound exhibits a melting point in the range of 180-183 C and demonstrates moderate solubility in common organic solvents such as toluene, hexane, and diethyl ether while being sparingly soluble in water. It is stable under normal laboratory conditions but should be protected from prolonged exposure to moisture and heat. Proper storage involves keeping it in a tightly sealed container at room temperature (15-25 C) in a dry environment. Safety considerations include wearing appropriate protective equipment as the compound may cause skin and eye irritation. Inhalation of dust should be avoided, and in case of accidental exposure, thorough washing with water and medical consultation is advised.
