Cinnamaldehyde has been tested as a safe and effective insecticide against mosquito larvae. [18] A concentration of 29 ppm of cinnamaldehyde kills half of Aedes aegypti mosquito larvae in 24 hours. [19] Trans-cinnamaldehyde works as a potent fumigant and practical repellant for adult mosquitos. [20] It also has antibacterial and antifungal ...
The European Parliament registered cinnamyl acetate as both a flavouring substance and a cosmetic compound in 1996. [14] [15] The Joint (FAO/WHO) Expert Committee on Food Additives described in 2000 that “the substance does not present a safety concern at current levels of intake when used as a flavouring agent”.

Nuclear magnetic resonance spectroscopy of stereoisomers most commonly known as NMR spectroscopy of stereoisomers is a chemical analysis method that uses NMR spectroscopy to determine the absolute configuration of stereoisomers. For example, the cis or trans alkenes, R or S enantiomers, and R,R or R,S diastereomers. [1] [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.
Cinnamyl alcohol or styron [2] is an organic compound that is found in esterified form in storax, Balsam of Peru, and cinnamon leaves. It forms a white crystalline solid when pure, or a yellow oil when even slightly impure.
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.
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]
