Used as a building block in organic synthesis for ligands bicyclic heterocycles pharmaceuticals and semiconducting materials like thienoisoindigo nanowires. Serves as HF NMR probe due to ortho-halogens.

Provides orthogonal halogen handles for directed ortho-metalation (e.g. with n-BuLiLDA) cross-couplings or self-assembly in nanomaterials via halogen bonding.

2-Bromo-6-fluorobenzaldehyde is a pale yellow to beige solid benzaldehyde derivative with bromine at position 2 and fluorine at 6 and low water solubility.
