چکیده
The title compound, C(6)H(6)N(2)O(2), was obtained as a product of an in vitro study of the metabolism of benzofuroxan. The molecule exhibits a amphi configuration of the oxime groups C=N-OH. One oxime group is involved in the formation of a strong intra-molecular O-H⋯N hydrogen bond, while another links mol-ecules into zigzag chains along the c axis via inter-molecular O-H⋯N hydrogen bonds.

In the title compound, [Cu(C(2)H(5)N(4)O(2))(2)(CH(3)OH)(2)]·2C(2)H(6)N(4)O(2)·2CH(3)OH, the Cu(II) atom, lying on an inversion center, is coordinated by four N atoms from two 1,2-diamino-2-hy-droxy-imino-ethanone oximate anion and two O atoms from two methanol mol-ecules in a distorted octa-hedral geometry. The two uncoordinating oxamide dioxime mol-ecules, each lying on an inversion center, a...
متن کاملBioassay of p-Quinone Dioxime for Possible Carcinogenicity (CAS No. 105-11-3).
p-Quinone dioxime, a rubber vulcanization accelerator, was selected for bioassay by the National Cancer Institute because of a lack of adequate carcinogenicity data. A bioassay for the possible carcinogenicity of p-quinone dioxime was conducted using Fischer 344 rats and B6C3F1 mice. p-Quinone dioxime was administered in the feed, at either of two concentrations, to groups of 50 male and 50 fem...
متن کاملDegradation of pentachlorophenol by Mycena avenacea TA 8480--identification of initial dechlorinated metabolites.
Cultures of the basidiomycete Mycena avenacea TA 8480 were shown to metabolize pentachlorophenol (PCP), 2,3,5,6-tetrachloro-p-hydroquinone (TeCHQ), and 2,3,5,6-tetrachloro-p-benzoquinone (TeCBQ). The first metabolite of the PCP degradation pathway was identified as TeCBQ which in a second reaction is reduced to the hydroquinone TeCHQ. Subsequently dechlorination of TeCHQ yielded 3,5,6-trichloro...
