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”. [1]
It is obtained from oil of cinnamon, or from balsams such as storax. [4] It is also found in shea butter. [citation needed] Cinnamic acid has a honey-like odor; [2] and its more volatile ethyl ester, ethyl cinnamate, is a flavor component in the essential oil of cinnamon, in which related cinnamaldehyde is the major constituent.
The commercial material often contains low levels of 2,6-di-tert-butyl-4-methoxyphenol as a stabilizer. It is a derivative of cinnamaldehyde with a hexyl substituent. One supplier reported that its hexyl cinnamaldehyde (or "hexyl cinnamic aldehyde") contained at least 90% trans isomer. [2]
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.
It is a derivative of cinnamaldehyde, featuring one hydroxy group and two methoxy groups as substituents. It is an intermediate in the formation of sinapyl alcohol , a lignol that is a major precursor to lignin .
Cinnamaldehyde is a naturally-occurring compound that has a conjugated system penta-1,3-diene is a molecule with a conjugated system Diazomethane conjugated pi-system. In theoretical chemistry, a conjugated system is a system of connected p-orbitals with delocalized electrons in a molecule, which in general lowers the overall energy of the molecule and increases stability.
Density: 1.018 g/cm 3: Melting point: −42 °C (−44 °F; 231 K) Boiling point: 224 °C (435 °F; 497 K) ... It is produced by the hydrogenation of cinnamaldehyde.
