The substance is also an important aroma component of aged beer and buckwheat. The odor of this substance is perceived as orris, fat and cucumber. 2-Nonenal is found in lemon. α-nonenyl aldehyde β-hexylacrolein FEMA 3213 C9H16O 140.2227 140.120115134 (2Z)-non-2-enal (2Z)-non-2-enal 2463-53-8 CCCCCC\C=C/C=O InChI=1S/C9H16O/c1-2-3-4-5-6-7-8-9-10/h7-9H,2-6H2,1H3/b8-7- BSAIUMLZVGUGKX-FPLPWBNLSA-N belongs to the class of organic compounds known as medium-chain aldehydes.
