4,6-Dichloro-5-fluoropyrimidine（Cat No.:L026296）is a halogenated heterocyclic compound featuring chlorine atoms at the 4- and 6-positions and a fluorine atom at the 5-position of the pyrimidine ring. This electron-deficient scaffold is highly reactive toward nucleophilic aromatic substitution, making it a valuable intermediate in the synthesis of pharmaceuticals, agrochemicals, and bioactive heterocycles. The presence of multiple halogens allows for selective functionalization, enabling the stepwise introduction of amines, alkoxides, or other nucleophiles. Its compact structure and versatile reactivity make it ideal for designing kinase inhibitors, antiviral agents, and other small-molecule drug candidates.
