The isopropylbenzaldehydes form a group of substances that are derived from both benzaldehyde and cumene (isopropylbenzene). The structure consists of a benzene ring with attached aldehyde  (-CHO) and isopropyl groups  (-CH (CH ₃ ) ₂ ) as substituents . Their different arrangement results in three constitutional isomers with the empirical formula C ₁₀ H ₁₂ O. They are mainly to be regarded as substituted benzaldehydes. 4-Isopropylbenzaldehyde is mainly known by its common name, cuminaldehyde . It is the only one found in nature and is one of the terpenes .
