- 291211 Acyclic aldehydes without other oxygen function — Methanal (formaldehyde)
- 291212 Acyclic aldehydes without other oxygen function — Ethanal (acetaldehyde)
- 291221 Cyclic aldehydes without other oxygen function — Benzaldehyde
- 291229 Cyclic aldehydes without other oxygen function — Other
- 291241 Aldehyde-alcohols, aldehyde-ethers, aldehyde-phenols and aldehydes with other oxygen function — Vanillin (4-hydroxy-3-methoxybenzaldehyde)
- 291242 Aldehyde-alcohols, aldehyde-ethers, aldehyde-phenols and aldehydes with other oxygen function — Ethylvanillin (3-ethoxy-4-hydroxybenzaldehyde)
