2,4,5-Trifluorobenzonitrile (CAS 98349-22-5, C7H2F3N) is a benzonitrile carrying three fluorine substituents on its aromatic ring. Supplied by Ossila at >98% purity as a colourless liquid, it is used to install a fluorinated benzonitrile unit into target molecules through nucleophilic aromatic substitution.
In medicinal chemistry, the compound has served as the starting material for a fluorinated analogue of the antibiotic platensimycin, prepared in eight steps with a 23% overall yield. Its multiple functional groups make it a convenient intermediate for active pharmaceutical ingredient (API) research.
In materials chemistry, it is a precursor for dinitrile monomers used to build polytriazine covalent organic frameworks (COFs). The resulting frameworks have been reported with a BET surface area of 733 m2/g and a CO2/N2 selectivity of 48.7 ± 1.2 at 272 K.
- Building block for introducing fluorinated benzonitrile segments by nucleophilic aromatic substitution.
- Precursor in the synthesis of APIs, including a fluorinated platensimycin analogue.
- Synthesis of dinitrile monomers for polytriazine covalent organic frameworks.
- Medicinal chemistry and biochemistry research.
