3-tert-Butylhydroxyanisole (3-BHA) is an antioxidant which can have a modulating effect on chemical carcinogenesis. Information concerning the metabolism of 3-BHA is incomplete. In the present study, the metabolites formed by incubating 3-BHA with liver microsomes from rats given beta-naphthoflavone by p.o. intubation were studied. Three metabolites were identified, two major metabolites and a ...

The title compound, C(22)H(28)Br(2)O(2), crystallizes in a staggered arrangement to minimize the inter-actions of its ortho substituents, with a dihedral angle of 84.2 (3)° between the two aromatic rings. Short C-H⋯O hydrogen-bonding inter-actions between meth-oxy groups result in a one-dimensional polymeric chain of mol-ecules lying parallel to the b axis. One tert-butyl group is disordered eq...
