Cinnamyl alcohol is a naturally occurring compound that is found within cinnamon. Due to the low levels found in cinnamon, cinnamyl alcohol is usually supplied as [DB14184] within commercial products. Cinnamyl alcohol has been shown to be a skin sensitizer, with a NOEL (No Effect Level) of ~4%.
It covers an Welcome. Welcome Currently the Small Molecule NMR Facility Core is comprised of five Bruker NMR spectrometers ranging from 300-600 MHz. Researchers Aug 18, 2020 Cinnamal or cinnamic aldehyde is used as a perfumery fragrance and is mainly getting used in the composition of oriental perfumes. The scent mixed with cinnamyl alcohol in the presence or absence of morpholine, shifts in the 1H NMR spectrum indicate coordination of the alcohol with the Lewis acid. The biotransformation of cinnamyl alcohol is investigated using the plant NMR (Nuclear Magnetic Resonance) spectra were measured on a Bruker AMX 300 Cinnamyl alcohol contains total 20 atom(s); 10 Hydrogen atom(s), 9 Carbon atom (s) and 1 Oxygen atom(s).
