Cuminaldehyde (4-isopropylbenzaldehyde) is a naturalorganic compound with the molecular formula C₁₀H₁₂O. It is abenzaldehyde with anisopropyl group substituted in the 4-position.

Cuminaldehyde is a constituent of theessential oils ofeucalyptus,myrrh,cassia,cumin, and others.^[1] It has a pleasant smell and contributes to the aroma of these oils. It is used commercially in perfumes and other cosmetics.

It has been shown that cuminaldehyde, as a small molecule, inhibits the fibrillation ofalpha-synuclein,^[2] which, if aggregated, forms insoluble fibrils in pathological conditions characterized byLewy bodies, such asParkinson's disease,dementia with Lewy bodies^[3] andmultiple system atrophy.^[4]

Cuminaldehyde can be prepared synthetically by the reduction of 4-isopropylbenzoyl chloride or by theformylation ofcumene.

Thethiosemicarbazone of cuminaldehyde has antiviral properties.^{[medical citation needed]}
