4-Bromo-2,6-difluoroaniline (CAS 67567-26-4) from Ossila is a fluorinated aniline building block supplied as a white powder with a purity above 98%. Its benzene ring carries a bromine atom in the para position and two fluorine atoms in the ortho positions relative to the amine, giving chemists several reactive sites to work with in a single molecule.
Each substituent offers a different synthetic route. The bromine handles palladium-catalysed cross-coupling for building larger molecules, while the amine can act as a nucleophile or be oxidised for the preparation of conjugated azo compounds. The fluorine atoms tune molecular orbital energy levels and can also take part in nucleophilic aromatic substitution when designing macromolecules.
Reported uses include a photo-switchable Pd-azobenzene complex that reversibly forms two distinct self-assembled structures, and quasiplanar triarylamine hole-transporting materials for perovskite solar cells and OLEDs.
- Intermediate for synthesising conjugated azo dyes and azo compounds.
- Precursor for triarylamine hole-transporting materials in perovskite solar cells and OLEDs.
- Building block for organic semiconductor molecules via Pd-catalysed coupling.
- Synthesis of photo-switchable self-assembled molecular architectures.
- Research into light-triggered drug release systems.
