Definition
ChEBI: (2E,6Z)-nona-2,6-dienal is an enal that is (2E,6Z)-nona-2,6-diene substituted by an oxo group at position 1. It has a role as a plant metabolite. It is an enal and a trans-2,3-unsaturated fatty aldehyde.
Allgemeine Beschreibung
trans-2,cis-6-Nonadienal is the key contributor to the cucumber flavor. It is also found in mango ripened anchovy and kelp. Unialgal cultures of various Synurophycean species for the occurrence of trans-2,cis-6-nonadienal have been investigated.
Sicherheitsprofil
Low toxicity by
ingestion and skin contact. A moderate skin
irritant. When heated to decomposition it
emits acrid smoke and irritating fumes.
