P-METHYLPHENYLACETALDEHYDE Usage And Synthesis
Chemical Properties
p-Tolylacetaldehyde has a characteristic green fruity odor reminiscent of sweet floral and forest-like and a corresponding flavor.
Uses
4-Methylphenylacetaldehyde (p-Tolylacetaldehyde) is used in perfumes, e.g., in soap, in tobacco fragrances, in the preparation of pesticides, etc.
Preparation
From p-methylbenzaldehyde; also from p-methylbenzyl chloride and hexamethylene tetramine.The methods of preparation correspond closely to those of phenylacetaldehyde. Thus, the compound can be prepared by glycidic ester synthesis from 4-methylbenzaldehyde and chloroacetate ester, by hydroformylation of 4-methylbenzylhalide with Co2(CO)8Na2CO3 in acetonitrile, or by oxidation of 4-methylstyrene.
Definition
ChEBI: (4-Methylphenyl)acetaldehyde is a member of phenylacetaldehydes.
Taste threshold values
Taste characteristics at 10 ppm: sweet, fruity cherry with spicy an nutty nuances.
