Frequently Asked Questions
No, it is a highly specialised technical term used almost exclusively in chemistry and fragrance industries.
Yes, it occurs naturally in some citrus oils and other plant sources, but is often produced synthetically for industrial use.
Its primary use is as a building block in fragrance and flavor compositions, adding citrus, floral, or waxy notes.
There is no difference. 'Dodecanal' is the systematic IUPAC name, while 'lauraldehyde' is a common trivial name for the same compound (C₁₂H₂₄O).
