Cinnamaldehyde is an organic compound with the formula C 9 H 8 O or C 6 H 6 CH=CHCHO. Occurring naturally as predominantly the trans ( E ) isomer, it gives cinnamon its flavor and odor . [ 1 ] It is a phenylpropanoid that is naturally synthesized by the shikimate pathway . [ 2 ]
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 ]
It is produced by the hydrogenation of cinnamaldehyde. The compound is used in many mechanistic studies. [1] It is a common substrate in organic synthesis. [2] [3]
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]
A 900 MHz NMR instrument with a 21.1 T magnet at HWB-NMR, Birmingham, UK Nuclear magnetic resonance spectroscopy, most commonly known as NMR spectroscopy or magnetic resonance spectroscopy (MRS), is a spectroscopic technique based on re-orientation of atomic nuclei with non-zero nuclear spins in an external magnetic field.
A nuclear magnetic resonance spectra database is an electronic repository of information concerning Nuclear magnetic resonance (NMR) spectra.Such repositories can be downloaded as self-contained data sets or used online.
While 1D NMR is more straightforward and ideal for identifying basic structural features, COSY enhances the capabilities of NMR by providing deeper insights into molecular connectivity. The two-dimensional spectrum that results from the COSY experiment shows the frequencies for a single isotope , most commonly hydrogen ( 1 H) along both axes.
