Cas no 2039-83-0 (1,2-dichloro-4-ethenylbenzene)
1,2-Dichloro-4-ethenylbenzene is a chlorinated aromatic compound characterized by the presence of two chlorine atoms at the 1 and 2 positions and an ethenyl group at the 4 position of the benzene ring. This structure imparts reactivity suitable for use as an intermediate in organic synthesis, particularly in the production of specialty chemicals, agrochemicals, and pharmaceuticals. The dichloro substitution enhances electrophilic aromatic substitution selectivity, while the ethenyl group offers versatility for further functionalization, such as polymerization or cross-coupling reactions. Its stability under standard conditions and well-defined reactivity profile make it a valuable building block for constructing complex molecular architectures in research and industrial applications.
