Hazard Information

Uses

2-(4-tert-Butylbenzyl)propionaldehyde may be used as a reference standard for the determination of 2-(4-tert-butylbenzyl)propionaldehyde in:

Human urine samples by ultra-high performance liquid chromatography-tandem mass spectrometry (UHPLC-MS/MS) equipped with electrospray ionization (ESI) source and multiple reaction monitoring (MRM) mode of detection.
Deodorants and air fresheners by sonication extraction coupled with gas chromatography-mass spectrometry (GC-MS).
Scented consumer products by GC-MS as well as GC in combination with olfactometry.

Uses

In addition to its applications in the perfume and aroma industry, lilial is used mainly for the synthesis of substituted 3-(4-tert-butylphenyl)-2-methylpropylamines, a new class of substances with fungicidal properties. These compounds are effective against mildew in barley and wheat.

Production Methods

Lily aldehyde is produced industrially almost solely by aldol condensation of 4-tert-butylbenzaldehyde and propionaldehyde to give 4-tert-butyl-α-methylcinnamaldehyde, which can be hydrogenated selectively on noble metal catalysts such as Pd, Rh, Pd – Pr2O3 on Al2O3, or on modified cobalt catalysts. The aldol condensation and the hydrogenation can be carried out in one step in the presence of a hydrogenation catalyst.
The Friedel – Crafts reaction of 4-tertbutylbenzene with methacrolein or methacrolein diacetate proceeds in an analogous manner to the preparation of cyclamenaldehyde.
Further possibilities are the Rh-catalyzed hydroformylation of 1-(4-tert-butylphenyl)-1- methoxypropene and subsequent partial hydrogenation, the palladium salt catalyzed reaction of 4-tert-butylphenylhalide with methallylalcohol, and the dehydrogenation of 3-(4-tert-butylphenyl)-2-methylpropanol on silver catalysts.

General Description

2-(4-tert-Butylbenzyl)propionaldehyde is categorized under the synthetic fragrance class of compounds widely utilized in consumer products such as perfumes, after shave lotions, cosmetics, etc.
