Cinnamaldehyde is used in agriculture because of its low toxicity, but it is a skin irritant. [25] Cinnamaldehyde may cause allergic contact stomatitis in sensitised individuals, however allergy to the compound is believed to be uncommon. [26] Cinnamaldehyde can contain traces of styrene, which arises during storage or transport. Styrene ...
Expanded polystyrene packaging A polystyrene yogurt container Bottom of a vacuum-formed cup; fine details such as the glass and fork food contact materials symbol and the resin identification code symbol are easily molded. Polystyrene (PS) / ˌ p ɒ l i ˈ s t aɪ r iː n / is a synthetic polymer made from monomers of the aromatic hydrocarbon ...
In polymer chemistry, chain transfer is a polymerization reaction by which the activity of a growing polymer chain is transferred to another molecule: [1] [2] + + where • is the active center, P is the initial polymer chain, X is the end group, and R is the substituent to which the active center is transferred.
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 + NADP + cinnamaldehyde + NADPH + H + Thus, the two substrates of this enzyme are cinnamyl alcohol and NADP + , whereas its 3 products are cinnamaldehyde , NADPH , and H + . This enzyme belongs to the family of oxidoreductases , specifically those acting on the CH-OH group of donor with NAD + or NADP + as acceptor.
Cinnamoyl-CoA reductase (EC 1.2.1.44), systematically named cinnamaldehyde:NADP+ oxidoreductase (CoA-cinnamoylating) but commonly referred to by the acronym CCR, is an enzyme that catalyzes the reduction of a substituted cinnamoyl-CoA to its corresponding cinnamaldehyde, utilizing NADPH and H + and releasing free CoA and NADP + in the process.

Figure 17: Inhibition of polystyrene propagation due to reaction of polymer with molecular oxygen. Nitrobenzene, butylated hydroxyl toluene, and diphenyl picryl hydrazyl (DPPH, Figure 18) are a few other inhibitors. The latter is an especially effective inhibitor because of the resonance stabilization of the radical. [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.
