2,4-Dichloropyrimidine（Cat No.:R005825）is a halogenated heterocyclic compound featuring chlorine atoms at the 2 and 4 positions of the pyrimidine ring. It is a valuable synthetic intermediate in pharmaceutical, agrochemical, and materials chemistry, frequently used in the preparation of substituted pyrimidines via nucleophilic aromatic substitution. The electron-deficient ring system makes it highly reactive toward amines, thiols, and alkoxides, enabling efficient formation of C–N and C–S bonds. Typically supplied as a crystalline solid or powder, 2,4-dichloropyrimidine is soluble in organic solvents and must be handled with care due to its irritant properties.
