NMR signal amplification by reversible exchange (SABRE) has been observed for pyridine, methyl nicotinate, N-methylnicotinamide, and nicotinamide in D2 O with the new catalyst [Ir(Cl)(IDEG)(COD)] (IDEG=1,3-bis(3,4,5-tris(diethyleneglycol)benzyl)imidazole-2-ylidene). During the activation and hyperpolarization steps, exclusively D2 O was used, resulting in the first fully biocompatible SABRE sys...

In the title compound, C(4)H(5)N(3)O(2), the nitro group is twisted with respect to the imidazole ring by a dihedral angle of 5.60 (2)°. Weak inter-molecular C-H⋯O and C-H⋯N hydrogen bonding is present in the crystal structure.

In the title compound, C(4)H(4)N(4)O(4), the two nitro groups are twisted with respect to the imidazole plane, making dihedral angles of 24.2 (3) and 33.4 (4)°. In the crystal structure, the mol-ecules are linked through non-classical inter-molecular C-H⋯O hydrogen bonds.

The title compound, [Mn6(C7H4NO3)5(CH3CO2)2(C4H6N2)4.62(C3H7NO)1.38]·(C2H5)2O·C3H7NO·CH3OH·0.49H2O or Mn(II)(OAc)2[15-MCMn(III)N(shi)-5](Me-Im)4.62(DMF)1.38·diethyl ether·DMF·MeOH·0.49H2O (where MC is metallacrown, (-)OAc is acetate, shi(3-) is salicyl-hydroximate, Me-Im is 1-methyl-imidazole, DMF is N,N-di-methyl-formamide, and MeOH is methanol), is comprised of five Mn(III) ions in the metall...

Buprenorphine, which is used in France as a substitution drug for opioid addiction, is widely abused, and several fatal cases have been reported. In order to confirm a recent intoxication or to establish retrospectively chronic abuse, a simple and reliable gas chromatographic-mass spectrometric method was developed and validated for quantitation of buprenorphine and its active metabolite norbup...

Bathophenanthrolinedisulfonate (BPS) complexes of technetium(I) of the type [Tc(CO)3(BPS)(L)]n (L = imidazole derivatives) were synthesized and evaluated both in vitro and in vivo. [99mTc(CO)3(BPS)(MeIm)]- (MeIm = 1-methyl-1H-imidazole) was prepared in near-quantitative yield using a convenient two-step, one-pot labeling procedure. A targeted analogue capable of binding regions of calcium turno...

A fundamental structural feature of benzimidazoles, a group heterocyclic, aromatic compounds, is the fusion six-membered benzene ring with five-membered imidazole moiety. Formic acid, Acetyl chloride, hydrazine hydrate, Benzene-1,2-diol, Glycolic Acid, Benzoyl Methyl Ethyl Benzamide, and other chemicals were utilized in this research study. In study different methods used such as TLC, IR spectr...

In this study, poly(allylphenol-co-methylmethacrylate-co-vinyl imidazole) (PAMV) terpolymer adsorbents were synthesized using the photopolymerization method with 1-vinyl imidazole, methyl methacrylate, and 2-allylphenol monomers. Structural surface analyzes of PAMV polymers obtained different mole ratios 1H-Nuclear Magnetic Resonance, Fourier-Transform Infrared Spectroscopy, X-Ray Photoelectron...
