The title compound, C(13)H(11)NO(3)S, was synthesized from methyl anthranilate, triethyl-amine and 2-thio-phenoyl chloride in benzene. The mol-ecular conformation is stabilized by an intra-molecular N-H⋯O hydrogen bond. The dihedral angle between the rings is 2.74 (12)°. In the crystal, C-H⋯O inter-actions link neighbouring mol-ecules into a three-dimensional network.
Two ionic liquids triethylammonium oleate and stearate were synthesized from fatty acids triethyl amine using two different methods (one step three methods). The yield rearch 68.8-74% method) 86.3% (three of 68.7-74.1 83.5% method). one method spends more time but less chemicals brings higher yield. FT-IR 1H-NMR spectra ILs obtained both was measured. results showed that synthesis doesn’t affec...
The title compound, C(10)H(10)N(2)O(2), was synthesized by the reaction of the oxime of 2-acetyl-pyridine and 3-bromo-propanoyl chloride in the presence of triethyl-amine. The mol-ecule adopts a nearly planar chain-extended conformation with the oxime group in a trans and the acryloyl group in an s-cis conformation. This conformation is stabilized by an intra-molecular C-H⋯N hydrogen bond. The ...
The title compound, C(14)H(11)ClN(2)O(3)S, with fused thiophene and pyran rings, was synthesized via the condensation of dihydro-thio-phen-3(2H)-one 1,1-dioxide and 2-(3-chloro-benz-yl-idene)malononitrile catalysed by triethyl-amine in ethanol. The thio-phene ring adopts an envelope conformation and the pyran ring is planar (r.m.s. deviation = 0.0067 Å). The dihedral angle between the pyran and...
The potential tridentate Schiff base ligand 2-[1-(2-pyridyl-methyl-imino)eth-yl]pyrrole (HL) was synthesized from the condensation of 2-acetyl-pyrrole with 2-amino-methyl-pyridine. The title compound, [Cu(C(12)H(12)N(3))Cl], was synthesized from HL and copper(II) chloride using triethyl-amine as a base to deprotonate the pyrrole NH group. The title compound is a monomer and the central copper(I...
In the crystal structure of the title compound, C(14)H(11)NO(3), isolated from the reaction of 2-bromo-1-phenyl-ethanone and pyridine-4-carboxylic acid using triethyl-amine as a base to deprotonate the organic acid, the mol-ecular packing is stabilized by C-H⋯π inter-actions involving the phenyl and pyridine rings. The C-C-O-C torsion angle for the linkage between the two carbonyl groups is -80...
A simple, rapid and precise reverse phase high performance liquid chromatography method was developed for the analysis of Almotriptan. Chromatographic separation of Almotriptan was performed by using a kromosil C18 column (250 x 4.6mm, 5 μm) as stationary phase with a mobile phase comprising of 1% Triethyl amine : acetonitrile:methanol: 05:55:40 (v/v) at a flow rate of 1.0ml/min and UV detectio...
An instrument to detect gaseous amines and ammonia is described, and representative data from an urban site and a laboratory setting are presented. The instrument, an Ambient pressure Proton transfer Mass Spectrometer (AmPMS), consists of a chemical ionization and drift region at atmospheric pressure coupled to a standard quadrupole mass spectrometer. Calibrations show that AmPMS sensitivity is...
