(E)-2-Furyl methyl ketone 2,4-dinitrophenylhydrazone

(E)-2-Furyl methyl ketone 2,4-dinitro­phenyl­hydrazone

Crystals of the title compound, C(12)H(10)N(4)O(5), were obtained from a condensation reaction of 2,4-dinitro-phenyl-hydrazine and 2-furyl methyl ketone. The mol-ecule displays a nearly planar structure, and the furan ring is slightly twisted by a dihedral angle of 12.62 (6)° with respect to the phenyl-hydrazone plane. The face-to-face separation of 3.287 (7) Å between parallel benzene rings of...

(E)-Methyl 1,3-thia­zol-2-yl ketone 2,4-dinitro­phenyl­hydrazone

Crystals of the title compound, C(11)H(9)N(5)O(4)S, were obtained from a condensation reaction of 2,4-dinitro-phenyl-hydrazine and methyl 1,3-thia-zol-2-yl ketone. Excluding two methyl H atoms, the mol-ecule displays a planar structure, the dihedral angle between the terminal thia-zole and benzene rings being 1.82 (8)°. The imino group links with adjacent nitro and thia-zole groups by intra-mol...

Methyl ethyl ketone and methyl isobutyl ketone not carcinogenic.

Methyl Ethyl Ketone and Methyl Isobutyl Ketone Not Carcinogenic The April 22, 1993, issue of Environmental Health Perspectives contained a commentary by Legator and Strawn entitled "Public Health Policies Regarding Hazardous Waste Sites and Cigarette Smoking: An Argument by Analogy." Although the article does not include any discussion of either methyl ethyl ketone (MEK) or methyl isobutyl keto...

1,5-Dimethyl-4-[(5-methyl-2-furyl)­methyl­ene­amino]-2-phenyl-1H-pyrazol-3(2H)-one

In the title compound, C(17)H(17)N(3)O(2), a derivative of 4-amino-anti-pyrine, the structure displays a trans configuration with respect to the imine C=N double bond. The pyrazoline ring is essentially planar and makes a dihedral angle of 55.80 (1)° with the phenyl ring.
