Two other isomers are also known: 2-trifluoromethylbenzaldehyde and 3-trifluoromethylbenzaldehyde. These compounds are derivatives of benzaldehyde with trifluoromethyl substituents. The CF 3 group enhances the electrophilicity of the formyl group and provides a label for analysis by fluorine-19 nuclear magnetic resonance spectroscopy.
2-Chloro-6-fluorobenzaldehyde is a halogenated benzaldehyde derivative with the formula C 6 H 3 ClFCHO. It is an intermediate in the synthesis of halogenated heterocyclic compounds. [ 1 ] [ 2 ]

When the activation energy for the isomerization reaction is sufficiently small, both isomers will exist in a temperature-dependent equilibrium with each other. Many values of the standard free energy difference, Δ G ∘ {\displaystyle \Delta G^{\circ }} , have been calculated, with good agreement between observed and calculated data.
Substituents add ortho to the amine in diethyl-(meta-trifluoromethyl)aniline and ortho to the fluoride in para-fluorobenzaldehyde; When multiple substituents are comparably activating, steric hindrance dominates regioselectivity. Substituents add ortho to the methyl group in para-(tert-butyl)toluene
