The related aldehyde cis-3-hexenal (leaf aldehyde) has a similar and even stronger smell but is relatively unstable and isomerizes into the conjugated trans-2-hexenal.

This compound has been recognized as a semiochemical involved in mechanisms and behaviors of attraction in diverse animals such as insects and mammals.

Human odor perception

A pair of two single-nucleotide polymorphisms, both in the gene for the OR2J3 odor receptor, strongly reduce sensitivity to this odorant.^[1]
