Methyl 3-carboxy-5-nitrobenzoate
The structure of the title compound, C(9)H(7)NO(6), is essentially planar [maximum deviation 0.284 (2)Å] except for the methyl H atoms. The crystal structure is stabilized by asymmetric O-H⋯O hydrogen bonds linking the hydrogen carboxyl-ates into pairs around the inversion centres. There is also π-π stacking of the benzene rings [centroid-centroid distance 3.6912 (12) Å].
متن کامل2-Methyl-5-[(3-methyl-4-nitrobenzyl)sulfanyl]-1,3,4-thiadiazole
The mol-ecule of the title thia-diazole derivative, C(11)H(11)N(3)O(2)S(2), has a butterfly-like structure and the whole mol-ecule is disordered with a site-occupancy ratio of 0.629 (4):0.371 (4). The mol-ecule is disordered in such a way that the 3-methyl-4-nitro-phenyl units of the major and minor components are approximately related by 180° rotation around the C-N bond axis. The dihedral ang...
متن کاملDirect Spectrophotometric determination of Vanadiu (V) using 5- methoxy-2-[[(4-methoxy-3, 5-dimethyl-2-pyridinyl] methyl] sulfinyl]-1H-Benzimidazole [ESMPZL]
Highly sensitive and selective direct spectrophotometric method is proposed for the determination of aluminium in various real samples. 5methoxy-2-[[(4-methoxy-3, 5-dimethyl-2-pyridinyl] methyl] sulfinyl]-1HBenzimidazole reacts with V(V) forming greenish yellow coloured soluble complex in aqueous dimethyl formamide which has a λmax at 410 nm in the pH range 4.0-7.0. The system obeyed Beer’s law...
متن کاملEthyl 4-anilino-3-nitrobenzoate
In the title compound, C(15)H(14)N(2)O(4), the aromatic rings are oriented at a dihedral angle of 78.33 (3)°. An intra-molecular N-H⋯O hydrogen bond results in a non-planar six-membered ring with a flattened-boat conformation. In the crystal structure, inter-molecular N-H⋯O hydrogen bonds link the mol-ecules. π-π contacts between the phenyl rings and both the phenyl and benzene rings, [centroid...

A new etherified 1-O-acetylbritannilactone (ABL) analogue 2 was semi-synthesized by a mild etherification reaction. The structure of the newly synthesized analogue was identified by 1H-NMR, 13C-NMR and HR-ESI-MS analysis. 2 exhibited similar cytotoxicity against HCT116, SGC-7901 and HeLa human cancer cell lines with ABL.
