2-(Bromomethyl)acrylic acid ethyl ester

CAS 17435-72-2

2-(Bromomethyl)acrylic acid ethyl ester (CAS 17435-72-2) illustrates how molecular structure determines chemical role. Ethyl 2-(bromomethyl)acrylate is an activated unsaturated ester containing both an alpha,beta-unsaturated ester system and a bromomethyl group attached to the alkene. Those two features give synthetic chemists several ways to form new bonds: the bromomethyl carbon can undergo nucleophilic substitution, while the activated double bond can participate in addition and polymer-related chemistry. The ester group also provides a functional handle for later hydrolysis or other transformations. Public exact-CAS information for CAS 17435-72-2 is primarily reagent and synthesis oriented rather than tied to a single commercial product. Its value is therefore best understood as a multifunctional building block whose bromine, alkene, and ester can be addressed selectively in carefully designed reaction sequences.
