Description

1-Bromo-2-chloro-4-fluorobenzene (CAS No. 110407-59-5) is a high-purity halogenated benzene derivative with the molecular formula C₆H₃BrClF. This compound is a valuable intermediate in organic synthesis, particularly in pharmaceutical, agrochemical, and materials science research. Its unique substitution pattern (bromo, chloro, and fluoro groups on the benzene ring) enables selective functionalization, making it ideal for cross-coupling reactions, nucleophilic substitutions, and as a building block for complex molecules. Available in >98% purity (GC), it is supplied in rigorously tested, sealed packaging to ensure stability and longevity. Suitable for use in Grignard reactions, Suzuki-Miyaura couplings, and other palladium-catalyzed transformations. Store in a cool, dry place under inert atmosphere to maintain optimal quality.
