Cuminaldehyde (4-isopropylbenzaldehyde) is a natural organic compound with the molecular formula C₁₀H₁₂O. It is a benzaldehyde with an isopropyl group substituted in the 4-position.

Uses and occurrence

Cuminaldehyde is a precursor to another commercially important fragrance, cyclamen aldehyde.^[2]

Cuminaldehyde has been investigated for inhibition of the fibrillation of alpha-synuclein,^[3]

Cuminaldehyde can be prepared synthetically by the reduction of 4-isopropylbenzoyl chloride or by the formylation of cumene.
