salicylaldehyde
Very lowTechnical/scientific
Definition
Meaning
A colorless, oily organic compound with the formula C₇H₆O₂, consisting of a benzene ring with hydroxyl and aldehyde groups; it is the simplest aromatic hydroxyaldehyde.
In chemistry and industry, salicylaldehyde is used as a precursor in the synthesis of coumarin, pharmaceuticals, fragrances, and as a chelating agent in coordination chemistry. It is also employed as an intermediate in organic synthesis and in the manufacture of certain dyes.
Linguistics
Semantic Notes
The term is highly specific to organic chemistry and related fields. It is not used metaphorically or in general discourse. The name derives from its structural relationship to salicylic acid (from Latin 'salix' for willow, as salicylic acid was originally isolated from willow bark).

Learning
Memory Aids
Mnemonic
Think: SALIcyl (like salicylic acid, from willow) + ALDEHYDE (the functional group). It's the aldehyde version of salicylic acid.
Conceptual Metaphor
None in common use.
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with 'салициловый альдегид' (correct) and 'салицилальдегид' (also correct but less common). Ensure the spelling reflects the chemical structure, not a direct cognate of 'aldehyde' alone.
Common Mistakes
- Misspelling as 'salicylaldehide' or 'salicylaldehyd'.
- Mispronouncing with stress on the first syllable (/ˈsælɪsɪl.../) instead of on 'ald'.

Frequently Asked Questions
Yes, it occurs in small amounts in some plants, like spiraea, and is a component of certain essential oils.
It has a characteristic bitter almond or phenolic odour.
It can be irritating to the skin, eyes, and respiratory system and should be handled with appropriate safety precautions in a laboratory.
Salicylaldehyde is a chemical intermediate; it can be converted into salicylic acid, which is a precursor to aspirin (acetylsalicylic acid).
