methyl 2-[[2-methyl-3-[4-(1-methylethyl)phenyl]propylidene]amino]benzoate Chemical Properties,Usage,Production

Chemical Properties

Yellowish viscous liquid, barely pourable at room temperature. Almost insoluble in water and Propylene glycol. Soluble in alcohol and perfume oils. Intensely sweet, fresh-floral odor of great tenacity, somewhat reminiscent of the flowers of the Lemon tree. Greener and more diffusive than Hydroxycitronellal-Methylanthranilate.

Uses

Finds some use in perfume compositions, probably ranking No. 3 among Schiff’s bases after Aurantiol and Acaciol. Its fresher odor type and less “Orangeblossom”’-character are its main assets.

Synthesis

Methyl 2-[[2-methyl-3-[4-(1-methylethyl)phenyl]propylidene]amino]benzoate is prepared by condensation of Cyclamenaldehyde and Methylanthranilate.
