This database included more than 700,000 NMR, IR and MS Spectra, statistics specific to the NMR spectra are not listed. The NMR data includes 1 H, 13 C, 11 B, 15 N, 17 O, 19 F, 29 Si, and 31 P. The data were in the form of graphically displayed line lists.
The 1 H NMR spectra were recorded at a resonance frequency of 400 MHz with a resolution of 0.0625 Hz or at 90 MHz with a resolution of 0.125 Hz. The spectral acquisition was carried out using a flip angle of 22.5 – 30.0 degrees and a pulse repetition time of 30 seconds. [4]
4-Bromobenzaldehyde, or p-bromobenzaldehyde, is an organobromine compound with the formula BrC 6 H 4 CHO. It is one of three isomers of bromobenzaldehyde . [ 3 ] It displays reactivity characteristic of benzaldehyde and an aryl bromide .
Benzyl bromide is used in organic synthesis for the introduction of the benzyl groups when the less expensive benzyl chloride is insufficiently reactive. [6] [7] Benzylations are often achieved in the presence of catalytic amounts of sodium iodide, which generates the more reactive benzyl iodide in situ. [3]
Nuclear magnetic resonance crystallography (NMR crystallography) is a method which utilizes primarily NMR spectroscopy to determine the structure of solid materials on the atomic scale. Thus, solid-state NMR spectroscopy would be used primarily, possibly supplemented by quantum chemistry calculations (e.g. density functional theory ), [ 1 ...
This reagent can be used, e.g. in the reaction with carbon dioxide to prepare benzoic acid. [4] Other methods involve palladium-catalyzed coupling reactions, such as the Suzuki reaction. Bromobenzene is used as a precursor in the manufacture of phencyclidine.
New research links omega-6 fatty acids, commonly found in seed oils, and colon cancer growth. But there’s more to the story—and study if you read it carefully.
1981: Invention of the SNIF-NMR method by Professor Gerard Martin, Maryvonne Martin and their team at the University of Nantes / CNRS [1]; 1987: Creation of Eurofins Nantes Laboratories - specializing in wine analysis, and purchase of operating the CNRS patent rights [1] (this patent is now public and the name “SNIF-NMR” is now a registered trademark [2]
