| Uses |
A component of essential oils, Nonanal possesses a strong fruity odor. Essential oils have varying effects from antibacterial activity to hypolipidemic activity. |
| Definition |
ChEBI: A fatty aldehyde formally arising from reduction of nonanoic acis. Metabolite observed in cancer metabolism. |
| General Description |
Clear brown liquid characterized by a rose-orange odor. Insoluble in water. Found in at least 20 essential oils, including rose and citrus oils and several species of pine oil. |
| Air & Water Reactions |
Sensitive to air. Insoluble in water. |
| Reactivity Profile |
1-Nonanal is an aldehyde. Aldehydes are frequently involved in self-condensation or polymerization reactions. These reactions are exothermic; they are often catalyzed by acid. Aldehydes are readily oxidized to give carboxylic acids. Flammable and/or toxic gases are generated by the combination of aldehydes with azo, diazo compounds, dithiocarbamates, nitrides, and strong reducing agents. Aldehydes can react with air to give first peroxo acids, and ultimately carboxylic acids. These autoxidation reactions are activated by light, catalyzed by salts of transition metals, and are autocatalytic (catalyzed by the products of the reaction). The addition of stabilizers (antioxidants) to shipments of aldehydes retards autoxidation. Polymerizes readily with sulfuric acid and oxidized to nonanoic acid. |
| Fire Hazard |
1-Nonanal is combustible. |
| Safety Profile |
A severe skin irritant. Combustible liquid. Mutation data reported. When heated to decomposition it emits acrid smoke and irritating fumes. See also ALDEHYDES. |
