Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with 'acetaldehyde' (ацетальдегид), a different compound.
- The '-aldehyde' suffix is directly translatable as '-альдегид'.
Common Mistakes
- Misspelling as 'acraldehyde' (missing 'c').
- Confusing it with the more common 'formaldehyde' or 'acetaldehyde'.
- Using it in non-chemical contexts.
