Chemical compound
Undecanal, also known as undecyl aldehyde, is an organic compound with the chemical formula C10H21CHO. It is an eleven-carbon aldehyde. A colourless, oily liquid, undecanal is a component of perfumes. Although it occurs naturally in citrus oils, it is produced commercially by hydroformylation of decene.[1]
It has been registered under the EU REACH scheme at >1000 tonnes by Oxea, which confirms the status as irritant.[2]
Undecanal is used in the synthesis of Disparlure.[3]
