Vinylbenzyl chloride (MF: C₉H₉Cl MW: 152.62) is an important bifunctional aromatic olefin compound. At room temperature, it exists as a colorless to pale yellow transparent liquid with a faint aromatic odor. Its chemical structure features a vinyl group (-CH=CH₂) and a chloromethyl group (-CH₂Cl) bonded to the para position of the benzene ring. Its core characteristic lies in possessing both a reactive vinyl group (polymerizable) and a chloromethyl group (substitutable), making it a key intermediate in organic synthesis and polymer materials.
