In the title coordination polymer, [Cd(C(7)H(4)N(3)O(2))(2)(C(3)H(7)NO)(2)](n), the Cd(II) atom, lying on an inversion center, is six-coordinated in a distorted N(4)O(2) octa-hedral geometry. The N atoms of the 4-nitrophenylcyanamide anions form the equatorial plane and the O atoms of the dimethyl-formamide mol-ecules occupy the axial positions. The anions act as bridging ligands, connecting th...

In the title compound, [Sm(C9I3O6)(C3H7NO)3] n , the Sm(III) atom is coordinated by nine O atoms, viz. six carboxyl-ate O atoms from three 2,4,6-triiodobenzene-1,3,5-tricarboxyl-ate (I3BTC) ligands and three O atoms from three N,N-dimethyl-formamide (DMF) mol-ecules. Each I3BTC ligand bridges three Sm(III) atoms, generating a three-dimensional metal-organic framework structure. The asymmetric u...

In the reaction of 7-chloro-1,5-benzodiazepine-2,4-dione with N,N-dimethyl-formamide/dimethyl-acetal, the diazepine seven-membered ring undergoes a contraction to form the five-membered ring. The reaction yields two isomers the title compound, C(13)H(14)ClN(3)O(2); the major component has the chlorine-atom substituent in the 5-position of the benzimidazolone ring and the minor component has the...

A new technique, which utilizes the chemical reaction between [32P]diimidazolidate of orthophosphate and the cetyltrimethylammonium salt of high-molecular-weight RNA in nonaqueous dimethyl formamide, has been developed for the 32P-labeling of RNAs after isolation. The radioactive label of high specific activity is introduced onto a phosphorylated 5'-end of the RNA and renders it suitable for 5'...

The aim of this work was to synthesize steroidal heterocycles and to elucidate the potential role of these compounds as antimicrobial agents. The synthesis of steroidal heterocycles containing the pyrazole, isoxazole, thiazole, pyrane, pyridine, pyridazine, or benzopyrane ring attached to the pregnene nucleus is reported. Progesterone (1) reacts with dimethyl formamide dimethyl acetal to form e...

The asymmetric unit of the title compound, [InCl3(C12H12N2)(C3H7NO)]·0.5H2O, contains two independent In(III) complex mol-ecules with similar structures and one lattice water mol-ecule. In each complex mol-ecule, the In(III) atom is six-coordinated in a distorted octa-hedral geometry, formed by two N atoms from the chelating 5,5'-dimethyl-2,2'-bipyridine ligand, one O atom from a dimethyl-forma...

Signal stability is essential for reliable multivariate data analysis. Urine samples show strong variance in signal positions due to inter patient differences. Here we study the exchange of the solvent of a defined urine matrix and how it affects signal and integral stability of the urinary metabolites by NMR spectroscopy. The exchange solvents were methanol, acetonitrile, dimethyl sulfoxide, c...

Effect of penetration enhancers were studied on the permeation of antihypertensive drugs prazosin hydrochloride and atenolol through full thickness skin of swiss albino mice. Atenolol was delivered to skin from saturated alcoholic solution containing 5% of 1-decanol and alcohol alone, while prazosin hydrochloride was saturated in dimethyl formamide(DMF, 5% v/v in water) and dimethyl sulfoxide(D...

The title compound, C(24)H(27)N(2)Si(+)·Br(-)·H(2)O, was synthesized from 1-(dimethyl-phenyl-silylmeth-yl)-1H-benzimidazole and (2-bromo-eth-yl)benzene in dimethyl-formamide. The benzimidazole ring system is nearly planar, with a maximum deviation of 0.015 (5) Å, and forms dihedral angles of 73.0 (3) and 39.6 (2)°, with the phenyl rings. In the crystal, mol-ecules are linked by O-H⋯Br, C-H⋯Br a...
