متن کامل4,4′-(Hexane-1,6-diyldioxy)dianiline
The complete molecule of the title compound, C(18)H(24)N(2)O(2), is generated by a crystallographic inversion centre. The torsion angles in the hexa-methyl-ene chain are consistent with an anti-periplanar conformation, whereas the conformation of the O-CH(2)-CH(2)-CH(2) unit is gauche. The three-dimensional crystal packing is stabilized by N-H⋯O and N-H⋯N hydrogen bonding.

Studies on the in vivo and in vitro disposition of 4,4'-[14C]-methylenebis(N,N-dimethyl)benzamine (reduced Michler's ketone, RMK) were performed. Osborne-Mendel rats retained, after 24 hr, 78% of a p.o. dose of [14C]RMK. At 24 hr after an i.p. dose, fat, liver, and intestine represented major sites for deposition of radioactivity. The major urinary metabolite of RMK, representing 36% of the tot...
