Abstract: A precursor compound of a fragrant aldehyde is provided, as well as a method of forming such a compound, a kit comprising said compound, and certain uses thereof. The precursor compound has formula (I), wherein A is a hydrocarbon residue of a fragrant aldehyde A-CHO; and X and Y are independently selected from the group consisting of a nitrile, a keto, and an ester functional group. One such precursor compound is ethyl 2-acetyl-4-methyltridec-2-enoate enriched in its Z-isomer, which is a thermally stable precursor of 2-methyl undecanal.
