Chemical Properties Of Alpha Methylstyrene Cas 98-83-9

Alpha Methylstyrene (MF: C9H10, MW: 118.18), features a molecular structure where a phenyl ring is connected to an allyl group. It belongs to the class of aromatic olefins and serves as a crucial organic chemical monomer. The presence of a carbon-carbon double bond in its molecule facilitates homopolymerization or copolymerization reactions. Due to its benzene ring, it undergoes Friedel-Crafts alkylation, acylation, and other aromatic substitution reactions; however, the double bond confers higher reactivity than pure benzene.
