Description

clear colorless liquid 2-PHENYLPROPIONALDEHYDE identified in dried mushroom, is a colorless liquid with a green hyacinth odor. Hydratropaldehyde can be hydrogenated to hydratropic alcohol, which is also used to a limited extent by reaction of p-ethylbenzyl chloride and isobutyric aldehyde in the presence of catalysts. The product is used in perfumes for, for example, household products. 2-Phenylpropionaldehyde has an intense, green, floral odor reminiscent of hyacinth.

Colourless to pale yellow liquid; Intense, green, floral aroma reminiscent of hyacinth

2-phenylpropanal is a member of the class of phenylacetaldehydes that is phenylacetaldehyde in which a hydrogen alpha to the aldehyde carbonyl group has been replaced by a methyl group. The major species at pH 7.3.
