3-Chloro-4-fluoronitrobenzene (TCI C1041, CAS 350-30-1) is a highly activated fluorinated aromatic building block bearing chloro, fluoro, and nitro substituents. The nitro group strongly activates the ring, allowing selective nucleophilic aromatic substitution at the fluorine position with amines, alkoxides, or thiolates. It is widely used to prepare substituted anilines and diversified compound libraries in medicinal and agrochemical research. AMI Scientific offers 25 g and 250 g packs; handle the solid in a fume hood and avoid dust formation during weighing.
