Phenylpropionaldehyde

Phenylpropionaldehyde, also known as 3-phenylpropanal, is an organic compound with the chemical formula C9H10O. It is an aldehyde derived from hydrocinnamic acid. This colorless to pale yellow liquid possesses a characteristic sweet, floral, and hyacinth-like aroma, making it a valuable ingredient in the fragrance industry.

Phenylpropionaldehyde is synthesized through various chemical routes, often involving the oxidation of 3-phenylpropanol or the hydroformylation of styrene. Its chemical structure consists of a phenyl ring attached to a three-carbon chain with an aldehyde functional group at the end.

The primary application of phenylpropionaldehyde is in perfumery and flavorings. It is used to impart floral notes, particularly those reminiscent of hyacinth, lilac, and narcissus, to a wide range of consumer products including soaps, detergents, cosmetics, and air fresheners. In flavor applications, it can contribute to fruit and spice profiles.

While generally considered safe for its intended uses, as with many aromatic chemicals, prolonged or excessive exposure to phenylpropionaldehyde in its concentrated form may cause skin or respiratory irritation. It is typically handled and used in diluted concentrations within finished products.
