Definition
Meaning
An organic compound, specifically dodecanal (C12H24O), a saturated fatty aldehyde with a 12-carbon chain, commonly found in some essential oils.
In perfumery and flavor industries, lauric aldehyde is valued for its waxy, citrus-like, and clean aroma, often used as a fragrance component. It's also a chemical intermediate in the production of other compounds.

Common Pitfalls
Translation Traps (for Russian speakers)
- Do not translate 'lauric' as лоурический; it's a root from 'lauric acid' (лауриновая кислота). The correct term is 'додеканаль' or 'лауриновый альдегид'.
Common Mistakes
- Misspelling as 'laurid aldehyde' or 'loric aldehyde'.
- Confusing it with lauric acid.
- Mispronouncing 'aldehyde' with a hard /h/ in British English.

FAQ
Frequently Asked Questions
It can be both. It occurs naturally in some essential oils (e.g., citrus, coriander) but is often produced synthetically for industrial use.
It is described as having a waxy, fatty, citrus-like, and clean odor, often compared to a faint lemon or candle wax scent.
The systematic IUPAC name is dodecanal.
As with many chemicals, it requires safe handling. Safety data sheets indicate it can be an irritant to skin, eyes, and respiratory system, and it is flammable.
