Definition
ChEBI: A member of the class of benzaldehydes that is benzaldehyde substituted by an isopropyl group at position 4. It is a component of essential oils from Cumin and exhibits insecticidal activities.
Taste threshold values
Taste characteristics at 10 ppm: spicy with green cumin and herbal nuances.
Sicherheitsprofil
Moderately toxic by ingestion and skin contact. A skin irritant. Combustible liquid. When heated to decomposition it emits acrid smoke and irritating fumes. See also ALDEHYDES.
Chemical Synthesis
Prepared synthetically by heating p-isopropyl benzoyl chloride with an aqueous or alcoholic hexamethylenetetraamine solution.
läuterung methode
A likely impurity is the benzoic acid. Check the IR for the presence of OH from CO2H, and the CO frequencies. If the acid is present, then dissolve the aldehyde in Et2O, wash it with 10% NaHCO3 until effervescence ceases, then with brine, dry over CaCl2, evaporate and distil the residual oil, preferably under vacuum. It is almost insoluble in H2O, but soluble in EtOH and Et2O. The thiosemicarbazone has m 147o after recrystallisation from aqueous EtOH, MeOH or *C6H6.
