Description

3-Chloro-5-fluoroaniline (CAS No. 4863-91-6) is a high-purity halogenated aniline derivative with the molecular formula C₆H₅ClFN. This aromatic amine is characterized by its chloro- and fluoro-substitutions at the 3- and 5-positions of the benzene ring, respectively, making it a versatile intermediate for advanced organic synthesis. Ideal for pharmaceutical, agrochemical, and materials science research, our product is rigorously tested to ensure ≥98% purity (HPLC/GC) with minimal impurities. Supplied as a light yellow to colorless crystalline solid or liquid (depending on storage conditions), it is packaged under inert gas to prevent oxidation. Compatible with coupling reactions, nucleophilic substitutions, and heterocycle formation. Available in quantities from grams to bulk kilograms with customizable packaging options.

Application

3-Chloro-5-fluoroaniline serves as a key building block in the synthesis of active pharmaceutical ingredients (APIs), particularly for fluorinated drug candidates targeting CNS disorders and antimicrobial agents. Its dual halogen functionality enables precise regioselective modifications in agrochemicals, such as herbicides and fungicides. Researchers also utilize it to develop advanced materials, including liquid crystals and conductive polymers, where its electron-withdrawing groups fine-tune electronic properties.
