Collection of ion-trap mass spectre of sulfonylurea pyrolysis products

The pyrograms of 14 sulfonylureas, i.e. herbicides characterized by high biological activity and low application dose are discussed and the mass spectra of over 30 relevant pyrolysis products as obtained with a heated filament pyrolyzer interfaced to a capillary gas chromatograph/ion-trap detector mass spectrometer are presented. Such a data compilation is useful for diagnostic purposes for both intact sulfonylureas and their metabolites after degradation in soil, because metabolites and pyrolysis products are often identical and most of their mass spectra are lacking in commercially available mass spectral libraries. The performance of the ion-trap detector based on the quality of the mass spectra is briefly discussed.

Because enzymes can increase reaction rates by enormous factors and tend to be very specific, Recommanded Product: 3-Methoxybenzo[d]isothiazole 1,1-dioxide, typically producing only a single product in quantitative yield, they are the focus of active research.you can also check out more blogs about 18712-14-6

SPECTROSCOPIC PROPERTIES AND PROTONATION EQUILIBRIA IN 1,2-BENZISOTHIAZOLES

The protonation equilibria of 1,2-benzisothiazoles, involving substituents at position 3, or the ring nitrogen at position 2, have been investigated by potentiometric and/or spectrophotometric methods.The values of the protonation constants (log Kobs) have been compared with values calculated according to the linear relationships of Barlin and Perrin.For compounds with substituents at position 3, the protonation constants have been determined potentiometrically.The presence of the benzisothiazole moiety induces an increase of base strength, with respect to that expected from the calculated substituent effects according to Barlin and Perrin.The protonation constants of the heterocyclic nitrogen at position 2 have been determined spectroscopically in very acidic solutions.The comparison of the values observed with those calculated following Barlin and Perrin for substituted isoquinoline shows that the ring nitrogen is less basic than expected.

One-Pot Synthesis of Unsymmetrical Bis-Heterocycles: Benzimidazole-, Benzoxazole-, and Benzothiazole-Linked Thiazolidines

A one-pot, three-component synthesis of benzimidazole-linked thiazolidines from 2-cyanomethyl benzimidazole, iso-, isothio-, or isoselenocyanates and 1,2-dichloroethane is reported. Isolation of the key intermediate formed during the course of the reaction validates its mechanistic pathway. Under the same reaction conditions, benzimidazole-linked/fused thiazinanes were obtained when 1,3-dichloropropane or diiodomethane was used.

Combinatorial design and virtual screening of potent anti-tubercular fluoroquinolone and isothiazoloquinolone compounds utilizing QSAR and pharmacophore modelling$

The virulence of tuberculosis infections resistant to conventional combination drug regimens cries for the design of potent fluoroquinolone compounds to be used as second line antimycobacterial chemotherapeutics. One of the most effective in silico methods is combinatorial design and high throughput screening by a ligand-based pharmacophore prior to experiment. The combinatorial design of a series of 3850 fluoroquinolone and isothiazoloquinolone compounds was then screened virtually by applying a topological descriptor based quantitative structure activity relationship (QSAR) for predicting highly active congeneric quinolone leads against Mycobacterium fortuitum and Mycobacterium smegmatis. The predicted highly active congeneric hits were then subjected to a comparative study between existing lead sparfloxacin with fluoroquinolone FQ hits as well as ACH-702 with predicted active isothiazoloquinolones, utilizing pharmacophore modelling to focus on the mechanism of drug binding against mycobacterial DNA gyrase. Finally, 68 compounds including 34 FQ and 34 isothiazoloquinolones were screened through high throughput screening comprising QSAR, the Lipinski rule of five and ligand-based pharmacophore modelling.

An approximate absolute 33S nuclear magnetic shielding scale

Sulfur-33 chemical shifts have been measured for a number of simple compounds, e.g.SF6, HFSO3, X2SO2, SO2, Cl2SO, CH3SH, H2S, and OCS, which have not been previously reported.Our results indicate that the range of 33S chemical shifts is approximately 1000 ppm, slightly less than that observed for 17O and approximately one half the range reported for 77Se.Using the 33S nuclear spin-rotation constant of OCS measured by molecular-beam electric resonance and Flygare’s procedure, an absolute 33S shielding constant of 843+/-12 ppm is calculated for OCS, permitting an approximate absolute shielding scale to be proposed for this nucleus.

Characterization of the key aroma compounds in proso millet wine using headspace solid-phase microextraction and gas chromatography-mass spectrometry

The volatile compounds in proso millet wine were extracted by headspace solid-phase microextraction (85 mum polyacrylate (PA), 100 mum polydimethylsiloxane (PDMS), 75 mum Carboxen (CAR)/PDMS, and 50/30 mum divinylbenzene (DVB)/CAR/PDMS fibers), and analyzed using gas chromatography-mass spectrometry; the odor characteristics and intensities were analyzed by the odor activity value (OAV). Different sample preparation factors were used to optimize this method: sample amount, extraction time, extraction temperature, and content of NaCl. A total of 64 volatile compounds were identified from the wine sample, including 14 esters, seven alcohols, five aldehydes, five ketones, 12 benzene derivatives, 12 hydrocarbons, two terpenes, three phenols, two acids, and two heterocycles. Ethyl benzeneacetate, phenylethyl alcohol, and benzaldehyde were the main volatile compounds found in the samples. According to their OAVs, 14 volatile compounds were determined to be odor-active compounds (OAV > 1), and benzaldehyde, benzeneacetaldehyde, 1-methyl-naphthalene, 2-methyl-naphthalene, and biphenyl were the prominent odor-active compounds (OAV > 50), having a high OAV. Principal component analysis (PCA) showed the difference of distribution of the 64 volatile compounds and 14 odor-active compounds with four solid-phase microextraction (SPME) fibers.
