The achiral planar (maximum deviation 0.014 Å) title compound, C(10)H(6)Cl(2)O(2), crystallizes in the chiral space group P2(1)2(1)2(1) in an arrangement incorporating conventional O-H⋯O hydrogen bonding leading to a supra-molecular chain.
In the title compound, C(4)H(6)F(4)O(2), a partially fluorinated aliphatic diol, cooperative O-H⋯O hydrogen bonds form R(2) (2)(14) rings, which are connected into infinite layers parallel to the (100) plane by C(7) chains. A C-H⋯F link is also seen.
We compared the metabolic activation in mouse skin of the weak carcinogen 6-methylchrysene, which lacks a bay region methyl group, and the strong carcinogen 5-methylchrysene, which has a bay region methyl group. Metabolites of 6-methyl-chrysene were prepared using liver homogenates and were identified by their spectral properties and by comparison to synthetic standards as dihydrodiols, hydroxy...
Benzo(a)anthracene (BA) and several benzo-ring deriv atives of BA were tested for their tumor-initiating activity on mouse skin. A single topical application of 0.1 to 2.0 /<mol of hydrocarbon was followed 7 days later by twiceweekly applications of the tumor promoter 12-O-tetradecanoylphorbol-13-acetate for 20 weeks. Comparisons of the percentage of mice with papillomas and the number of papil...
